As shown in the video: The following video contains stunts performed by trained professionals on a closed course under strict supervision. Any attempt to recreate these activities could result in (wait for it) injury, death and significant damages to personal property.
It gets better: And you would forever be known as the person who died trying to imitate something from the internet. Don't try this at home.
Monty and Frank dressed as Yakuza members and kicking the shit out of Gus and Geoff.
How Burnie prepares Geoff & Gus for the "Video Game Foods" challenge: by getting them completely drunk, then waking them up at 5 AM.
Geoff: I fuckin' hate all of you.
Burnie: I think it's amazing that you guys can roll out of bed and immediately start drinking.
Gus: I didn't stop drinking! I, like, took an hour break and laid down!
As soon as they see the massive meal set up for them, they immediately go for the beer.
The challenge is decided by one bite of pizza that had earlier been described as "smelling like cat food," "smelling like a cat's ass," and "tasting like a gym floor." Gus pretends to take a bite, and Geoff does (thus winning)... then immediately throws up.
Geoff: You guys are assholes.
Gavin and Michael trying to beat a genuine racecar driver by racing him in a videogame (while he's driving them around in the real thing) and still failing.
At one point, Michael gets disoriented and drives the wrong way, setting them back about a quarter of a lap. Gavin also gets disoriented when he takes over and, somehow, turns them around correctly.
Gavin being screamed at by Michael for not getting back in the car quickly enough.
Michael throwing up in the car, then throwing Gavin off by putting the vomit in his face. Then chasing him around with the bag after the race is finished.
Gavin's (empty) vomit bag flying out the car window towards the end of the final lap. Fortunately, he doesn't need it.
"You ever drink milk and eat Cheetos before a race?" "Oh hell no."
After throwing up, Michael gives his "last wishes":
Michael: Tell my family I hate them, tell Lindsay that she was okay, it was a good run, uh, but... I don't want to leave her anything, I don't want to leave her anything, I want everything to be buried with me.
Gavin and Michael are using each other as target practice to determine whether or not screen looking would be a legitimate strategy in real life combat, but in this situation, Michael manages to fall down the same hole on THREE separate occasions.
The paint grenades.
Michael: I grenaded myself!
Some of Gavin's running during the test is pretty damn funny too.
The second round includes NP Cs as played by Lindsay and Barb in the watchtower. Neither Michael or Gavin know this until they're shot by them.
At one point Gavin is hiding around a corner and can see from Michael's point of view that his fellow Lad might be lurking on the other side of it. How does he safely test whether this is the case? By sticking his leg around the corner.
After the test Michael asks if he's allowed to shoot the girls now the test is over. Burnie says yes and both Lindsay and Barb flee as Michael comes after them with his paintball gun.
