Zero sleep.

(Keith crying)

- [Keith] Ugh, I feel awful!

- We are going to be driving while sleep deprived.

- Yeah, I've, I've done that one.

Whoopsie doopsie!

- [Ned] Now this isn't something you think of as like

an intoxication, right?

- Out of all the things we're testing,

I know this is the one that I've

actually come close to crashing.

- So, we've designed a course with twists

and turns and surprises and we're going

to test ourselves to see how do we do

under four different influences.

- I have no idea how this is gonna turn out.

(upbeat rock music)

(crash)

- [Keith] Oh wow.

- Oh wow.

(upbeat trumpet music)

(yawning)

(sirens)

(screaming)

- Oh my god!

- Sleep deprived driving, I think is as

dangerous as driving while impaired with

any alcohol or other substance.

- [Detective Bill] And it's a very big

problem in the United States.

In the year 2016, 824 people died

as a consequence of driving drowsy.

- If you deprive yourself from

sleeping for twenty four hours,

it's almost the same as if you were at a point one

in an alcohol breathalyzer test.

My advice is, don't drive if you're sleep deprived.

- That said, we're going to do it.

- Ah, sleepover time!

- Sleepover time!

- To get sleepy, we are having the first ever

Try Guys official sleepover party!

- My wife is out of town and she took

the baby and the dog with her.

Got a little chickie, cheep, cheep!

- Things are about to get weird!

We're gonna wear onesies,

we're gonna have a pillow fight,

we're gonna draw a dick on whoever falls asleep first,

but first we're gonna dance!

(upbeat techno music)

- Then turn around.

(laughing)

(crash)

- When I'm sleepy I get a little more manic.

Mainly because I'm also taking

large amounts of caffeine.

- [Keith] Wow! There you have a butt slap.

- [Ned] Oh, boys.

- [Keith] So you can fuck each other while

dressed as tigers, obviously.

- I'm notorious for pulling a lot of

all nighters and it's bad, it's dangerous.

- Well it's commonly known as drowsy driving.

If somebody gets involved in a traffic collision,

they might have a civil implication

in the state of California.

It's legal, but it's not safe.

- Keith wake up! - Oh, god.

- No sleeping tonight!

- Sleepy Keith is the full on monster.

I just suck at everything.

I don't think I could do math.

I love math!

(crash)

- I become a giant baby-man, when I'm sleepy

and I knew, some of you were thinking

I'm a giant baby-man to begin with,

go, go right and fuck yourself right in the,

right in the face.

- Go turtle, go turtle go!

(screaming)

- Being a new father,

I'm not getting much sleep these days.

- We see people who are involved in traffic collisions

because a family had a brand new baby

and they're deprived from sleeping

that culminated in terrible consequences.

- [Ned] I probably average about four, five hours

of sleep a night.

- Seven to eight hours of sleep is ideal

for most people for proper functioning

of our health, our judgment.

- [Eugene] Were you sleeping?

- No.

(crash)

- Video games keep me awake.

- [Eugene] Yeah, yeah, flex, work that butt girl.

She a robot but she dangerous.

- I'm a car playing soccer.

(crash)

- Don't, don't!

- We have chemicals in our brain that help us

stay awake at the right time and then

we have chemicals in our brain that get

released to tell us, you know what,

it's time to go to sleep and make us sleepy

and when we start altering our behavior to

change those chemicals we can definitely get

into trouble and that can impair our driving on the road.

(crash)

- [Eugene] Yeah!

- [Keith] That is so scary.

- Now we're watching a scary movie.

- [Eugene] Ned doesn't like scary movies.

- Ned has never seen The Conjuring,

we told him it's a delightful romp.

- [Eugene] You're with us, Ariel isn't here.

We're watching The Conjuring.

- This is the worst night of my life.

(laughs)

Oh, Jesus.

(laughs)

(crash)

(gasp)

- Oh shit.

- This is gonna get merked.

(crash)

- [Eugene] How sleepy are you?

- On a scale of one to 10?

10.

(laughs)

- [Eugene] Where did Ned go?

(crash)

- My little chickie,

do you guys want to see how I take care of Wes

in the middle of the night?

- We have a homeostatic mechanism kind of like

an air conditioning system where the more we stay awake,

the more our body wants to sleep.

So our brain starts sending chemicals

to us saying, "go to sleep, go to sleep, go to sleep."

- There we are in the nursery!

A fresh diaper!

Wipe, wipe, wipe our little chickie!

It's your diaper!

(laughs)

[Eugene] You're not gonna put a diaper

on a (words drowned out by laughter.)

- The ability to focus is impaired by sleep deprivation,

the ability to concentrate,

the ability to make good judgments is also impaired.

(laughs)

- [Keith] This is so scary.

(laughs)

- [Ned] Get out, lets get out, lets get out of here.

(gasps followed by mocked screams)

(crash)

(crash)

- I guess this seems like a good place

to lay down my foundation!

(laughs)

(backwards speaking)

- It's my house.

(crash)

(fake cryin)

- I feel awful.

(laughs)

(creepy children singing with multiple animal noises)

(dramatic, suspenseful music)

- Oh, my god. - Sorry.

- You just smashed my dick.

(laughs)

- [Lady On A Bull Horn] Kieth it's time to get up and drive.

- But Zach is so cute!

(sirens) (Keith and Zach screaming)

(sirens over music)

(Keith screaming)

- Six-one-thousand.

- [Lady On A Bullhorn] Let's walk, heel toe, heel toe.

You think this is a joke?

- I'm not sure, it's very loud.

- How do you like it?

(laughs)

(dramatic music)

- [Ned] We have set up 538 cones in

a complicated traffic course.

Since this is science, two days ago we did a control

where we each drove the course sober,

but today we haven't slept for 36 hours.

- My strategy is I drank a shit-ton of caffeine.

There's a lot of people out there that wake up really early,

drink a lot of coffee, that's what I'm representing.

I do this all the time.

- What's the difference between staying up all night

and waking up all night with a baby?

- I just wanna get this over with so I can go back to bed.

(laughs)

(sirens) (screams)

- Ready to fuck up this course.

- Do you want me to go? Do you want me to go?

Do you want me to go? Do you want me to go?

Do you want me to go? Okay.

- Okay, lets go.

Ohh, I'm driving a car.

- [Together] Yay! There he goes!

- (sighs) okay, just a normal evening with me following

my golf cart friend home.

- I just said that I didn't think I was that tired,

but then I got into this car and I got ready to drive,

and I'm pretty tired.

- Easy does it, easy, easy.

- [Keith] Oh, this is tough.

Oh, was there just a dip in the road?

- This is nonsense.

- [Eugene] This is easy.

(mumbles,) I've done this a million times.

Here we go, perfect.

(exhales)

- Oh, fuck!

Fuck!

- [Together] Ohhhh.

- If you're sleep deprived,

you're really not able to pay attention.

It almost acts like a central nervous system depressant.

- [Eugene] Oh, shit.

- That was an early wake up call.

- You're not able to concentrate,

so even if you're awake,

the ability to focus is impaired by sleep deprivation,

the ability to concentrate,

the ability to make good judgments is also impaired.

- Ohhhh.

(honking)

- Dog.

- I drive sleepy so often,

and once I get coffee in I'm like,

"I can do anything!

I can take over the world!"

- Drinking coffee may have an effect.

- This is a trenta sized coffee,

that's the equivalent of an entire wine bottle.

- But also, it may only be good for a short amount of time.

- Okay, oh shit.

- And he completely blew a stop sign.

- And the danger in that is that you may have a micro-nap.

- Oh, sorry.

- Oh, that's too much caffeine.

Okay, oh fuck, okay.

- They can culminate in a traffic collision.

- Fuck.

- Oh, fuck, that was the stop sign.

Whoopsy doopsy!

- I wonder if I can just pull off

to the side of the road here and take a quick little nap.

- Where the fuck is Ned going?

- He's left the course.

- Oh, no.

- So if someone wants to take a nap,
