[Dan narrating on-screen text]

[suspenseful music]

- [Dan] Imagine being swallowed whole

by a 60,000-pound sea monster.

- The whales open their mouths wide and surge up

and take a big gulp.

[videographer gasps]

- Before they can react,

it actually takes them under the water.

[kayakers yelling]

- Or learning the hard way

that dogs aren't very good drivers.

- That sweet, adorable Boxer dog jumps

through the driver's side door and lands on the accelerator.

- Suddenly, the van is hurling backwards towards James.

- How about being in the middle of a fight

between a snake and a hawk?

- The snake coils even tighter around Peggy's arm,

and that hawk is persistently pecking at the snake.

- Peggy's arm is going through it.

She's like, "Jesus, take the snake and the hawk."

- [Dan] These are the freak accidents so strange,

they are truly "Unbelievable."

[suspenseful music]

- Any homeowner knows DIY projects can be dangerous,

but next time you whack your thumb with a hammer

and mutter every swear word under the sun,

you'll want to remember the story of Forthman Murff,

and realize it could be a lot worse.

[foreboding music]

- Forthman Murff is a guy that likes doing hard work

and he's a guy that likes doing the job by himself.

He's a 74-year-old retired lumberjack.

And Forthman has decided to retire to a multi-acre property,

where he's far away from everything,

and he's surrounded by trees.

- One day, he looks up at a hundred-foot tall tree

on his property and decides its day has come.

Forthman fires up the chainsaw and is ready to get to work.

[chainsaw rumbling]

- He performs this technique that's called notching,

where he expertly cuts this V-shape

into the side of the tree,

where he wants the tree to fall.

And then on the other side,

he makes this horizontal cut.

- [Dan] With the chainsaw still roaring,

Forthman steps back to admire his work.

- The tall tree tips over just like he wants it to,

but as it falls,

[tree creaking]

it hits the massive limb

of another tree nearby.

The rogue limb comes crashing down

and slams into Forthman's shoulder,

knocks him back 10 feet.

- He ends up falling into this ditch.

- Then another nearby tree falls

and crushes his foot and breaks his leg,

but he has not let go of the chainsaw.

- He twists his body and he ends up landing on his face.

He blacks out.

- [Dan] A few seconds later, Forthman wakes up to a sound

he's never heard before.

- The chainsaw is still running

and he can tell it's cutting something,

but it's not wood.

He sits up, he looks down,

and he notices there's this giant pool of blood.

- [Dan] That's when he's hit with an excruciating pain.

- Somehow, as he was falling,

still holding onto the chainsaw,

he manages to land on top of it with his neck.

- And it continued to cut through his windpipe,

his esophagus, and muscles,

and now his head is only held on

by his carotid artery and his spine.

- Forthman realizes that the only way he's gonna be saved

is by getting to his truck.

Problem, his truck is 150 feet away,

which means he now has to hop all the way to his truck

while also maintaining the integrity of his severed head,

literally holding it on top of his neck

so it doesn't fall off.

- As he's hopping along, he's struggling to breathe.

The saw has cut his esophagus and his windpipe,

and things keep filling up with blood.

So every so often he has to stop, lean forward,

lift his head like a Pez dispenser

so he can clear his airways of blood,

so he can breathe again.

- Miraculously, he makes it to the truck,

opens the door, turns the key,

and starts driving the half a mile to his neighbor's house.

- [Dan] Despite being shocked by the gruesome sight,

Forthman's neighbor drives him to the nearest hospital,

20 miles away.

- When they get there, this hospital is a rural hospital.

It is not equipped to put a man's head back

onto his shoulders and neck properly.

- So they put him in an ambulance

and tell him he's gotta go to a bigger hospital

in Tupelo, 30 miles away.

- [Dan] Two hours after the accident,

Forthman finally makes it to Tupelo,

but he's barely hanging on.

- Forthman goes through six surgeries

to reattach his head and fighting off all sorts

of infections along the way, and he makes it.

- Unbelievably, after all of these surgeries,

seven months later, he's able to talk and breathe

and speak completely normally.

Forthman's surgeon can't even believe it

and says with his injuries,

he shouldn't have even survived

if that had happened in the hospital parking lot,

let alone two hours away by himself in the forest.

- Forthman Murff lives another 18 years

and continues cutting down trees until the age of 92,

still using that same chainsaw.

While his miracle survival is one in a million,

at a Sacramento ice cream parlor, the odds aren't so kind.

- It's a beautiful Sunday in September

and the Golden West Air Show is in full swing

at the Sacramento Executive Airport.

- There are about a thousand airplane enthusiasts

and families watching from the ground

as all kinds of military planes, old aircraft,

as well as experimental, newer planes buzz around

and do various tricks in the sky above.

- [Dan] By 4:30 PM, the show comes to an end

and spectators are looking to make a fun afternoon

a little bit sweeter.

- Across the street from the air show

is a place called Farrell's Ice Cream Parlor.

There's a huge crowd, many of them coming from the air show,

and they're gathered enjoying some ice cream

with family and friends.

- And one of the coolest things about it

is that it's located directly in line

with the end of the runway.

So while you're enjoying a banana split,

you can actually watch the planes taking off

right above you.

- [Dan] Back on the tarmac, pilots from the air show

are ready to head home, including Richard Bingham,

and his vintage Korean War era F-86.

- The F-86 is one of the fan favorites.

This airplane is built for dog fighting,

and the cool thing about that airplane

is that it's actually seen combat during the Korean War.

- Bingham, who is a very seasoned pilot,

taxis to his runway position.

Then on command, he throttles up,

and speeds down the runway.

- And about a third of the way down the runway,

things start to go bad.

He goes to lift the nose of the airplane up,

and for some reason, he can't get airborne,

and he's still cruising across the ground

in excess of 150 miles an hour.

- Bingham tries to abort the takeoff,

but it's too late for that.

He runs out of runway.

- [Dan] In a matter of seconds,

the F-86 speeds past the runway

and through a chain link fence,

causing the external fuel tanks to explode.

- The plane is now on fire, completely out of control.

It crosses the street and crashes through a passing car.

- [Dan] Both people in the car are instantly killed,

but this freak accident doesn't end there.

- This out of control fireball

plows through a parking lot and slams violently

into the crowded Farrell's ice cream shop.

- An explosion rips through the ice cream parlor.

It's like a missile that's torn through it.

- Inside, people are pinned under pieces

of plane and roof, many of them already dead.

It looks like a war zone.

- [Dan] Firefighters are quick on the scene

and able to save 28 people,

but many others aren't so lucky.

- 23 souls are lost that day at the ice cream parlor

and countless more are injured.

As for Richard Bingham, miraculously, he survives.

As he's being carried to safety with a broken leg and arm,

he begs the first responders, "Don't save me,

save the people in the fire."

- [Dan] It appears to be a powerful moment of selflessness

until the truth behind the accident is revealed.

- In a later FAA investigation, Richard testifies

that he'd only spent three and a half hours

in the cockpit of this plane,

yet still claiming prior to the flight

that he'd mastered the aircraft.

- Richard is a master pilot.

He's got over 2,000 hours under his belt, but in Learjets.

This is a military aircraft.

Experts say you need 100 hours minimum to become proficient

in a Cold War era fighter plane like this.

- Due to his inexperience flying this airplane,

he had no idea that the F-86, the way it's designed,

is you can't be aggressive

in bringing the nose of the airplane up

before you get the right amount of speed.

Had he had more experience flying it,

he would've known when that nose comes up too quickly,

you kill all the airflow over the wings,

causing the airplane not to be able to generate lift,

destroying your chances of being able to take off.

- By the end of the investigation,

while Richard Bingham isn't criminally charged,

he does have his pilot's license revoked.

- While a tragic day,

the Farrell's ice cream disaster compels the FAA

to impose heavy restrictions

on retired military aircraft operating

in densely populated areas.

- Our greatest pleasures often come

from the simplest things.

For a young Ukrainian lab tech, it's chewing bubblegum.

But his obsession for never ending flavor backfires

in a truly unbelievable way.

- Vladimir Likhonos is a 25-year-old student

at Kyiv Polytechnic Institute with a passion for chemistry.

- He's there training to become a scientist,

but he has a habit of taking chemicals home from the lab.

- Not because he's trying to steal them

or for any nefarious purposes,

he's just very, very into the study of chemistry.

- [Dan] That passion even extends to Christmas break

when Vladimir's home for the holidays.

- Vladimir spends a lot of time in his bedroom at home,

running various experiments.

And while he does, he chews a lot of gum.

- Like a lot of people, Vladimir hates it

when you're chewing your gum and all the flavor disappears.

It's just like chewing cardboard.

- [Dan] Luckily, Vladimir figures out

how to solve this problem using chemistry.

- On his desk next to his computer,

he keeps a little saucer of powdered citric acid.

Citric acid is incredibly powerful.

It's a flavor enhancer for candies and sodas.

And when he dips his gum in it

and puts it back in his mouth, it restores his flavor.

- He has his lab stuff strewn all around his room.

And in this particular day,

next to his saucer of citric acid powder,

he has a little baggy of another powder from his lab.

- Vladimir is so focused on his work

that while he's dipping and chewing, dipping and chewing,

he accidentally dips into the other bag.

And then puts the gum back in his mouth

and continues chewing.

- [Dan] Without warning, that small mix up

triggers a violent explosion.

[explosion echoes]

- His brother, Rostislav, goes into Vlad's room

to check on what had happened.

And when he gets there,

he sees the most horrifying thing

you could ever imagine.

He sees his brother Vlad sitting in his chair,

blood covering his face,

because his lower jaw is completely missing.

- It turns out the other powder

that he had dipped his gum in was an explosive.

- It's later discovered that Vlad,

in addition to being very passionate about chemistry,

also had an affinity for making his own fireworks.

- While the actual name of the explosive powder

was never released, it's estimated

that it was four times more powerful than TNT.

- Many speculate that it could be tert-butyllithium

or cyclonite because both of those are white powders

that react explosively to pressure.

- So while Vlad is chewing this gum,

which has been dipped in this chemical,

the act of chewing compresses all

of these explosive molecules repeatedly,

which causes it to explode.

- Police and paramedics rush to the house,

but by the time they get there, it's too late.

Vladimir's dead.

- A lot of the first responders

that arrived on the scene described it

as one of the most terrifying things

they've ever encountered.

- Death by bubblegum is awful,

but two years later, on the other side of the world,

another man finds himself

in a different kind of bubble trouble.

- Steve McCormack is a truck driver

from Opotiki, New Zealand, which is on the north island,

and it's a small town that's miles

from the nearest hospital.

- Steven is at work standing behind his truck cab,

hooking it up to a trailer,

something he's done a thousand times before.

- [Dan] It's just another day on the job

until one small misstep changes that.

- All of a sudden, Steven slips.

And he feels a sharp pain in his left buttock.

And at first he thinks, oh, he fell on a nail

or something sharp.

- Then he hears a whoosh sound of compressed air.

He turns to see what he's fallen on and it's not good.

- [Dan] It's a high pressure air hose

that's now embedded in his rapidly expanding left buttock.

- Within seconds, the valve is releasing air

into his body up to a pressure of 160 PSI.

That's more than twice enough

to burst the tires of his truck.

- [Dan] The air pressure is so powerful

that Steven starts to inflate.

- His skin is pulling taut and expanding.

- Skin's not supposed to do this.

Yeah, does skin expand when one is pregnant or gains weight?

Yes, but this is done over a period of time.

Not instantaneously.

The pain is excruciating.

In a matter of minutes, he's twice his normal size.

- His face is unrecognizable.

Even his eyes are getting bigger.

And one of them, he loses sight.

- His bosses rush over to see what is going on.

The valve is still embedded in him,

and Steven is howling in pain.

- He's so firmly affixed to this nozzle

that his bosses can't pry him from it.

His skin is expanded around it.

- [Dan] With no way to pull the hose out,

they quickly shut off the air supply.

- Now after they're able to stop

the air flow going into Steve,

his coworkers are actually able to lift him

off of the valve and lay him on his side,

which is a good start.

There's just one problem.

The air isn't coming out of Steve.

- His bosses put ice packs on him

to help relieve his suffering,

but he is laying there in agony for over an hour

before medics finally arrive.

- When the emergency service gets there,

their first thought is let's give him

something for the pain.

So they try to put something in one of his veins,

but the pressure from the air inside his body

just shoots the needle right out.

- When the doctors examine Steven,

they realize that the air from the compressor

has filled his body cavity,

it's separated muscle from fat,

and it's putting pressure on his heart and his lungs.

- One thing the doctors do note right away

is how lucky he is because if that valve

had hit an artery or a vein, it would be deadly.

But thankfully, it was just embedded

in the fat tissue of his buttock, which saved his life.

- Doctors insert a tube through Steven's ribs

and into his lungs to help him breathe.

- So the tube was able to help him breathe better,

but it didn't do anything about all of the air in his body.

Oh, no, unfortunately, he would have to wait

for it to pass the old fashioned way,

through belching and flatulence.

- After three days in intensive care

and an inordinate amount of passed gas,

Steven is restored to his normal size

in one of the most bizarre accidents

the doctors have ever seen.

- Except for a small puncture scar,

Steven walks away good as new,

and with a bloated reputation to match.

Forever known as the real-life Michelin man.

- When you've got a dog, excitement is

part of the package.

Unfortunately, that exuberance

can sometimes have unexpected consequences.

- 68-year-old James Campbell lives in Florida

and he loves his pet Boxer.

- What's not to love about a Boxer?

His squishy little face, a little knob tail.

It's his best friend.

- So one lovely day, James and his wife, Iris,

decide they're gonna hop into their 1995 Chevy van

and head out to get some errands done.

- Iris hops in the driver's seat,

'cause she's gonna back the van down the driveway,

and then James will get out and open the gate.

- As she's always done, Iris has the van in reverse

with her foot on the brake, and she opens the door

so she can keep an eye on James

to know when the gate's open, so she knows when to back up.

- And at that very moment, the couple's 70-pound Boxer

comes barreling through the yard,

wondering where his owners are going.

- And then while Iris's door is open,

that sweet, adorable Boxer dog jumps

through the driver's side door, down to the floorboard,

and lands squarely on the accelerator.

- Suddenly, the van is hurling backwards towards James.

- Iris tries everything to stop the van, but it's no use.

The van hits James, runs him over,

and ultimately, traps him underneath the wheels.

- [Dan] When paramedics arrive,

they find James completely crushed by the van.

They believe he died instantly.

- You can't blame the parents, you can't blame the dog.

It's just a tragic, awful, unbelievable,

and bizarre accident.

- Being run over by your own car is certainly ironic,

but it pales in comparison to the man

who meets his maker by way of his own money maker.

- When you watch someone ride a Segway,

it's almost like they're defying the laws of physics.

They're kind of floating by.

- In the 2000s, Segway is a growing company.

People are using them all over the place.

Tourists and mail people, even cops are using them.

- [Dan] By 2009, perhaps no one is a bigger fan of the Segway

than British millionaire, Jim Heselden.

- At 62 years of age, Jim Heselden is a guy,

who just loves to ride his Segway.

There's not a morning that goes by,

where he doesn't have his morning roll

through his neighborhood of West Yorkshire in England.

- Jimi's is truly a rags to riches story.

He spends his youth in the slums of Leeds.

And at 15, he starts working as a coal miner.

- Growing up in the coal mines,

Jim becomes pretty rough and tumble,

but he also has a few good ideas

and sort of fancies himself an inventor.

- In 1989, he comes up with an idea that makes him rich.

It's a gigantic foldable container

to be used on the battlefields.

- These containers become a huge hit

with militaries all around the planet.

And by 2009, Jim's become one

of the wealthiest people in Britain.

He's worth about half a billion dollars.

- [Dan] That's when Jim goes all in

on his favorite pastime.

- Jim loves his Segway so much that on Christmas day, 2009,

he buys the fledgling Segway Inc.

And being the owner of the company

doesn't change a thing for Jim.

He's still out there writing his Segway every morning.

- So nine months after Jim buys the Segway company,

he's rolling around on a hilly dirt road near his home

that he's very familiar with.

He's rolled on it hundreds of times.

As he's on his roll, he notices about 50 feet away,

there's a dog walker approaching him.

- So as Jim gets closer to the dog walker,

he decides to be courteous and let him pass,

so he backs up just a little bit to give him room to pass.

- Jim backs up his Segway just a hair too far,

and he and his beloved Segway

go careening down this 42-foot drop

complete with jagged rocks and tree limbs,

and he ends up falling face first,

dead in the river wharf below,

his Segway floating nearby.

- For Segway, this is terrible PR.

The hard truth is anytime after Jim's death,

every time you saw a Segway,

all you could really think was,

"Hey, didn't the owner of the company die on one of those?"

- It's a really unfortunate story.

This was a guy who was loved by his community,

poured money into the town,

and he even employed 350 people in Leeds

to work at his factory.

- [Dan] Jim Heselden's tragic fate reminds us

that it is sometimes the things in life

we love the most that hurt us in the end.

- Ah, the monotony of household chores.

What some of us wouldn't give for a little excitement

to save us from the drudgery.

A Texan named Peggy Jones would tell you

to be careful what you wish for.

- Peggy Jones is out riding her lawnmower in Silsbee, Texas,

just having a good time living life.

When all of a sudden, out of nowhere,

a snake falls from the sky directly onto Peggy.

- Clearly, the snake is just as frightened as Peggy is

because it wraps around her arm and then lashes at her face.

- [Dan] The snake clings desperately to Peggy

as she tries to fight it off.

As bizarre as this aerial anomaly is,

it's about to get even stranger.

- As she's fighting with this snake,

she hears this crazy loud screech coming from above.

[hawk screeching]

- When she looks up, she sees a hawk,

and it starts diving directly in her direction.

- The hawk latches itself onto Peggy's arm

and starts pecking at the snake.

- [Dan] Peggy's now caught in the crossfire

of a ravenous raptor and a snake,

who's determined to go down fighting.

The snake coils even tighter around Peggy's arm

and that hawk is persistently pecking at the snake,

but it just keeps missing and hitting Peggy's poor arm.

- Clearly, the hawk had caught the snake

and was planning on eating it for lunch, but it dropped.

And now, it wants its snake back.

- Suddenly, the hawk flies away.

Peggy's like, "I've been saved,"

but the hawk just does a couple circles

and then dive bombs it again.

- It's the same horror show over and over again.

Peggy's arm is going through it.

Peggy just wants to mow her lawn.

She is like, "Jesus, take the snake and the hawk."

- [Dan] Finally, the hawk gets a grip on the snake

and flies away with its lunch.

- Although, she's relieved that the snake and hawk are gone,

when she looks at her arm,

she realized that she's suffering deep puncture wounds.

She has scratches.

She's covered in bruises.

She runs to the house, she screams for her husband,

and he drives into the emergency room.

- The doctors in the emergency room do not believe

that this woman has not been stabbed.

It looks identical to wounds

that would be sustained from a knife.

- And he just kept on it and kept on it,

and I just couldn't get rid of the snake.

- This is the first time they've seen a hawk attack

on a human like this.

This is probably gonna be the last time they'll see this.

- Lucky for Peggy, she makes a full recovery.

The snake does not.

If Peggy's tale cautions us to keep our heads up

while mowing the lawn, the next one warns lucky fishermen

to keep their mouths shut.

- It's just another day at Boscombe Pier in Bournemouth,

and 28-year-old fisherman, Sam Quilliam,

is out with his friends

and they're hankering for some Dover sole.

- Sam casts his line, he gets a bite, he reels it in,

and him and his buddies are ecstatic

that they've caught a fish.

- When Sam pulls the fish up over the pier,

sure enough, it's a Dover sole.

- [Dan] With his catch secured,

next is the most important part.

A tradition that's been practiced by

anglers for decades. Time to pucker up.

- Sam holds the fish up to his mouth

and has done what so many fishermen before him have done.

He plants a big smooch right there on the sole.

- [Dan] Unfortunately for Sam, this is one flirty fish.

- The fish squirts out of his hand like a bar of soap,

and it goes the only direction it can go,

directly into Sam's mouth.

- This fish moves fast.

Instinctually, it's thinking it's returning to the water.

So within a matter of seconds, it's down past his molars

and it lodges itself in Sam's throat.

- Sam is in an all-out panic because he can't breathe

and he starts running around like a chicken

with his head cut off.

- Sam's friends, Steve and Matt, at first, are laughing.

They think it's a joke,

but they quickly realize that he's in trouble.

They try to grab the fish, they reach into his throat,

but they can't get it.

- The fish has fins around his body

and they fold in one direction allowing it to go in forward,

but if you try to pull the fish back out,

they open up and so that prevents them

from pulling it out of his throat.

- [Dan] Soon, Sam's turning blue,

and ultimately, passes out. -Sam goes into cardiac arrest.

One of his buddies attempts to perform CPR

while the other is calling emergency services.

It is chaos on this pier.

- The paramedic arrives within three minutes.

And when they see what's going on, they're in shock.

They've never seen a fish lodged

in someone's windpipe before.

The paramedic grabs some forceps

and attempts to go in there and pull the fish out,

but they have the same problem his friends have.

It's stuck.

- Finally, after seven tries,

he's able to pull the fish, in its entirety,

from Sam's mouth.

- [Dan] On the way to the hospital,

medics in the ambulance successfully revive Sam,

leaving him with an unbelievable story to tell.

- After he gets out of the hospital,

Sam returns to the scene of the kiss

to thank the paramedic who saved him.

- I've never seen anything like it.

- Also, to take photographs

with the fish that almost cost him his life.

- When asked if he will ever kiss a fish again,

Sam says he will, but only if they are too big

to fit in his mouth.

- The Old Testament speaks of a prophet Jonah,

who spent three days in the belly of a whale.

While nobody has since matched this feat,

two California kayakers come closer

than probably anyone wants to.

- It's a gorgeous and calm Monday morning

in San Luis Obispo Bay.

Making the day extra special,

20 enormous humpback whales have been spotted.

- Kayakers and paddle boarders are flocking to the bay

with the hopes of watching the animals feeding.

- Two women, Julie McSorley and her friend, Liz Cottriel,

are enjoying Julie's two-person kayak.

- [Dan] That's when the two ladies

spot a massive humpback whale just below the surface.

- Julie, for one, is thrilled at the sight

of these real life giants and wants to go in

for a closer look.

- Liz, on the other hand, is a lot more hesitant,

but Julie assures her that nothing bad will happen.

- [Dan] Liz finally agrees to go.

Meanwhile, just below the surface,

something very big is getting ready for lunch.

- Humpbacks feed on what are known as bait balls,

giant dense swarms or schools of fish

that gather near the surface.

When the whales are ready for a bite,

they open their mouths wide

and surge up through the bait balls and take a big gulp,

taking whatever fish they can catch.

- Julie and Liz are getting

an incredibly close front row seat to this amazing sight.

But maybe they're a little too close

because the women suddenly find themselves surrounded

by a very frightened school of fish.

- And before they can react, suddenly.

[tense music]

[water sloshing]

Their entire kayak is lifted up into the sky.

[kayakers gasping]

- [Videographer] No.

- Engulfing their entire kayak,

with the two women inside the boat.

- Julie and Liz are now in the mouth of this 50-foot,

60,000-pound humpback whale,

and it actually takes them under the water.

- [Dan] Although, it's a truly terrifying scenario,

there's actually a silver lining.

- Unlike sharks or orcas, humpback whales

do not have teeth. They use frilly plates called baleen

to filter small fish and crustaceans from the water.

They couldn't swallow a human

because their throat is only the width

of an average grapefruit.

- The whale very quickly realizes

that something in it's mouth that shouldn't be there.

So it spits out Julie and Liz,

and they find themselves popping up to the surface

of the water with their kayak upside down

right next to them.

Surprisingly, they are completely unharmed.

- If there's any question just how close

these women got inside this whale,

as they're walking to their car,

Liz shakes out her shirt and a bunch of fish fly out.

- When Julie and Liz get back to their vehicle,

Julie checks her pockets,

and it appears there is one casualty on the day.

Her car keys are missing.

- While kayaking the high seas

might seem a bit on the adventurous side,

sometimes, even the most benign tourist activities

can take a catastrophic turn.

- It's a busy Saturday in a suburb of Barcelona,

and a father and his young son are enjoying a stroll.

They're walking along the center of the city

and they come across something

that would be cool to any kid.

It's a recent installation,

a giant, 20-foot paper mache statue of a Stegosaurus.

- The dad sees this as the ideal time to get a selfie,

so his kid poses near the dinosaur, and suddenly,

they're hit with the most foul rotten stench.

- [Dan] That putrid smell seems to be coming

from the depths of the dinosaur.

- The father starts investigating.

He's looking all around this dinosaur

and he notices a crack in the back right leg

of the Stegosaurus.

- He looks in the crack on the Stegosaurus's leg,

it's the body of a dead man,

upside down inside the Stegosaurus,

and he is horrified. - So instead of taking a selfie,

the guy dials emergency services,

all while wondering just how this guy got in there.

- Police arrive at the scene

and soon investigators pieced together

the unbelievable story of the man's final moments.

- A few days prior, a man was walking

through the town also taking photos

when he sees the giant paper mache Stegosaurus.

- Much like the father and son who found his body,

he's fascinated by it.

- [Dan] It's believed that he then decides to reach

into the dinosaur to take photos of the inside.

- And then he accidentally drops his phone,

and it falls inside the dinosaur's body.

- The man who obviously wants his phone back

crawls inside the belly of this Stegosaurus,

and he sees this faint glow coming up

from the back right leg.

- Desperately, he's reaching deeper

and deeper into the leg, trying to grab the phone.

- And then he slips, falls and smashes head first

into the ground, probably killing him instantly.

- [Dan] That's where he remains for the next two days,

stuck inside the Stegosaurus leg.

- After the man is discovered by the kid and his father,

firefighters decides to open the statue

and remove the dead body.

- Police immediately identified the body

as that of a 39-year-old man, who was reported missing

by his family just days earlier.

- Turns out, extinct or not,

dinosaurs are mighty dangerous.

- As gender reveals get more creative,

some ideas do not go as planned.

Like one dad-to-be in Arizona,

whose vision turns into a nightmare in seconds.

- In Arizona, south of Tucson,

a guy named Dennis Dickey is there with his wife,

who is very, very pregnant.

Now surrounding them is all of their friends and family,

and they have been assured they're about to see

the most exciting gender reveal ever done.

- Out in the brush, about a hundred feet away

from any of their friends and family is a giant box,

and it's labeled boy or girl.

- Now Dennis, who happens to be

a U.S. border patrols agent who's off duty,

pulls out his rifle.

And he takes aim at the box.

- [Dan] After missing his first three shots,

the fourth time is a direct hit.

- The box explodes.

And it releases a giant powerful plume of blue smoke.

It's a boy!

- Unfortunately, the explosion doesn't just let out

a cloud of blue smoke.

Fire immediately catches the surrounding dry brush.

- Within seconds, the flames are out 30 feet

in every direction.

Dennis Dickey runs to the fire,

which is already out of control,

and he's trying everything he can to put it out.

He's throwing dirt on there.

He's trying to stomp parts of it,

but nothing is working.

- Start packing up.

- And the blaze just keeps growing and growing and growing.

- You gotta feel bad for the mom.

She's celebrating that she's having a boy,

but on the other hand, her husband just started a wildfire

that ends up burning 47,000 acres

of Coronado National Forest.

- How did he possibly create

such a massive explosion with one bullet?

Because days before, Dennis had stuffed the box

with something called Tannerite.

It is something very similar to TNT.

It's an explosive charge that ignites

when it's hit by a projectile like a bullet.

- Immediately after accidentally setting off the fire,

Dennis does the right thing

and turns himself in to authorities.

While the Sawmill Fire causes $8 million in damage,

Dennis Dickey is ordered to pay $220,000 in restitution

and serve five years probation.

- Of course, gender reveals aren't the only celebrations

that can end in chaos.

A century earlier, college football fans

found that out the hard way.

- It's Thanksgiving Day in San Francisco

at Recreation Park Stadium.

It's the game of the year between rivals,

Cal Berkeley Golden Bears and the Stanford Cardinals,

and everyone within a 30-mile radius wants to be there.

- The battle between Cal and Stanford

is actually one of the oldest college football rivalries

in the United States.

It dates back to 1892,

and it comes to be known as the Big Game.

- [Dan] The stands are packed to the brim

with nearly 20,000 spectators.

But outside, thousands more are trying to get in.

- So now you have all these fans,

who can't get into the game,

and they're now looking for anywhere to catch a glimpse.

- Turns out, they're in luck.

Recreation Park is in an industrial part of the city

that has a lot of tall buildings.

From some of these roofs, you can get a good look

into the stadium and all the action on the football field.

- [Dan] But the best view is from the San Francisco

and Pacific Glassworks factory,

just across the street from the stadium.

- Now it being Thanksgiving Day,

there's really only a skeleton crew working at this factory.

And regardless, you can't really do anything

about droves of college students trying to get on this roof.

- [Dan] About 400 young men climb onto the roof,

just in time for the 2:30 PM kickoff.

- You've got scores of fans up there,

but this metal corrugated roof held up with wooden slats

is not really designed to hold hundreds

and hundreds of cheering football fans.

- About 15 minutes into the game,

some of these fans start to hear these little creaks,

these little cracks in the rooftop,

but they're not really paying too much mind

because people are cheering.

They're yelling, they're screaming.

- A few moments pass and then a loud crack.

The crowd scrambles to find safety, but it's too late.

- [Dan] As the roof gives way under the heavy weight,

fans begin plummeting into the factory.

- Now luckily, the majority of the people on the roof

fall only a few feet onto the wooden slats

that are holding up the roof.

But unfortunately, not everyone is as lucky.

- Because this is a glassworks company,

they have a giant 500-degree Fahrenheit furnace

burning inside, down below.

- Surrounding that giant furnace is this metal grate

that some of the spectators actually fall onto

and get tangled up in.

And because this metal grate

is only a few feet away from the furnace,

they are slowly and agonizingly burning to death.

- [Dan] Some survive the fall, only to face another horror.

- The fuel pipes in the factory are severed

and cut open by the falling debris from the roof,

causing a sprinkler-like effect of this burning hot oil

to scatter all around the factory.

- Everyone in the stadium is so caught up in the game

that it doesn't even register to them,

the mayhem that's happening just next door.

- Ultimately, the event claims 23 lives.

All young men and hundreds more are injured.

The 1900 Thanksgiving Day accident goes down

as the deadliest disaster in American sports history.

- Whether it's almost choking to death

on the catch of the day, or coming within an inch

of complete decapitation via chainsaw,

these are the freak accidents

that are so surprising.

They are truly "Unbelievable."
