(body slams against ground) (crowd yells)

- That boy got turnt, though.

(robust dance/rap music)

- UFC gym. Sears Outlet.

I know where I'm going.

- Today we are here at a UFC gym to meet

some professional UFC fighters and fight each other.

(yelling and screaming) (playful background music)

- I have no fighting experience,

I got punched in the nose once in fifth grade.

- I've hurt someone's feelings.

- Apparently, Eugene has trained in martial arts.

That's not fair.

- (laughs) I feel like Zach might squeal

like a little piggy and it really excites me.

- If nobody gets hurt, that's a miracle.

(aggressive rock music)

What I know about UFC.

People from all kind of fighting backgrounds

come into an octagon and they,

hang out for three minutes or so.

- When I watch it on YouTube, it gets me going.

- So yeah, if I'm going to be beat up by anybody,

it might as well be a UFC champion, right?

- I'm Chuck, "The Iceman", Liddell,

former UFC light-heavyweight champ.

- Hi Chuck!

- UFC broke onto the scene in 1993,

as just a way to battle different styles against each other.

What we found out is, the best style is

a combination, is putting them all together.

- When you reach the UFC, you're the top of the top.

- And I feel like it's the true physical

and mental game of chess.

- Kicking ass is what I do for a living.

- [Everyone] Whoooooo.

- People like to watch other people fight.

- For us, how can we possibly do well at this?

- I mean, I'm lookin at you guys have the body of a god.

- You mean like Cupid?

- Like Zeus baby.

- Zeus? - [Anthony] - Zeus,

my man right here, you gonna be Zeus.

(robust dance/rap music)

- [Bruce Buffer] Anthonyyyy "Rumble" Johnsonnnnn.

- When I get ready for a fight,

or when I'm walking to the cage,

I don't think about anything,

I just know I got somebody I gotta beat up.

- Just get zen.

- Yeah, I'm like it's just a fight.

What's the worst that can happen?

(punches landing)

- [Voiceover] Oh, another big shot. Another one.

- I can think of some pretty bad things that could happen.

- Are you like scared to get hit?

- Absolutely.

(foot hitting pad)

(laughing and yelling)

- Cause when I punch people, I don't punch them

just to give 'em a little love tap. (screams)

- Oh, oh my god.

- When I punch 'em I'm actually trying to hurt them

with every single bit of my soul.

(punches landing on bag)

- Yeah.

One, two.

- Percentage-wise strength, what are you at right now?

- Ten.

(laughing)

- You want to go to 50?

- I could, but I don't want to break your shoulder.

- Any last words--

- Wait, can we all kick Zach real quick?

(kicks landing on pad)

- Owww.

- And I'm back.

- And you're back.

- And I'm back.

- So, first and foremost,

tell us how you got into the sport.

- I went to college, tried to play soccer and,

I hated it.

- Wrestled in high school, wrestled in college.

- So soccer just wasn't violent enough?

- I think it was like the first time

I ever knocked the goalie down I was like, wait a minute.

- You know, they gettin' a good workout,

they can defend themself on the streets,

I was like, I'ma give this a shot.

- And, just from Day 1, I just fell in love with it.

- A guy saw me and he goes,

"hey, want to learn how to do Mixed Martial Arts?".

I said, "sure why not?", and started taking classes,

and that's how it began.

- I come here and lift the arm up,

go underneath the crotch.

- I hate this, I hate this.

- [Bruce Buffer] Lightweight champion of the world,

Mighty Mouse.

- Do you think it's gonna be really easy

or really hard to take down somebody as strong as me?

- Uh, very easy actually.

- (screams) Oh, no! My brain!

- Is this fucking amateur hour right now?

- It is. It's definitely amateur hour.

No, I missed my guard!

- It's always better to, make somebody give up and tap out

because it's like, "fuck, you got me".

- When you go here, you want to massage the achilles tendon,

and when you have it, you go here.

(screams in agony)

- That hurts so much.

- Now, what I gonna do is I'm gonna take his foot,

and put it in my armpit.

And I'm going here and I'm just gonna fall down.

- Like this.

(crowd yells)

What's your tactic?

- I will take it somewhere,

to where the other person is not good.

So, when you're here, his objective is to posture up.

And I can jump up here.

I do not endorse this at all, ok.

This right here I do not endorse.

- On the flip side, what was your worst personal injury?

- I got cut and it was, probably started from like here,

all the way down to my cheek.

- I broke my rib in a Muay Thai fight.

- Had my eyeball split open.

(nauseated groans)

- What!?

- And I remember walking back to the corner,

it would just pop in and out, and I would just be like,

and when I would breathe, I'd be like...

- And his finger went right in my eye.

(nauseated groans)

Yeah, they showed a replay, and you can see

where the guys finger goes missing in my eye.

(screams of disgust)

- What's the worst injury you've ever had?

- I got my penis caught in my zipper.

(painful groans)

- Oh, no!

- Not in a fight?

- No, that smokes it all.

- [Bruce Buffer] Chris Weiiiiidmannnn.

- I don't know if I've ever met anyone

who's a champion, of anything.

- Don't let me intimidate you. Come on.

- [Voiceover] And he got it. Just like that.

- I actually have a broken pinky right now.

- That's pretty bad, man.

- I figured I can dance around and I can kick a lot.

(kicks landing)

- The first kick we're gonna do

is the real basic, Muay Thai, kick.

(screams in pain)

I gotta step out on an angle,

which opens up my hips to turn my body.

(grunts)

(kick landing)

- Do you ever do jumping kicks?

- Yeah, you can do jumping kicks.

(knee landing)

(screams and laughter)

- My wife really didn't want me to do this today.

- So that means she cares for you.

- Yeah, that's true. - [Chris] That's nice,

my wife would probably make me do this,

just so I feel pain.

Grab the neck. - [Ned] Oh God.

- Nice and tight, you can shake them a little bit.

It comes down to who's smarter, it's all about deception.

Is your wife gonna like this?

- Yeah, I think so.
