The cast performs various crazy stunts for our amusement.

[opening line]
Johnny Knoxville: Hi, I'm Johnny Knoxville. Welcome to "Jackass"!
Chris Pontius: I'm not into bestiality, but that's a good-looking animal.
[after Ryan has jumped several times into a river in winter]
Bam Margera: Are you cold?
Ryan Dunn: You're an idiot.
Johnny Knoxville: I have a full grown, semi-nude man bound with duct tape in my truck and I was trying to get out to the desert to bury him. How do I get to 5 South?
[Johnny is arguing with a parrot]
Johnny Knoxville: Don't tell me to fuck off, say "Jackass".
Johnny Knoxville: In the movie Cool Hand Luke, Paul Newman eats fifty hard boiled eggs without puking in one hour. We didn't think that was possible, so we staged our own little contest to see if any man OR woman could eat fifty eggs without puking. Well one thing; in our contest we encourage puking.
Man on the street: God bless you.
Chris Pontius: [dressed up as Satan] God didn't bless me. He wrote a bunch of fibs about me.
Bam Margera: Oh, dude ! My fucking tailbone is seriously broken ! I'm not even kidding !
Ryan Dunn: He broke his tailbone... That's alright, we don't have tails anymore, what's the point of having one ?
Bam Margera: Phil gets off work in ten minutes, and I've got twenty paintballs up in this bitch. He's gonna die.

Steve-O: I'm not looking forward to this *at all*!
Steve-O: [while asking a passenger for a butt piercing] She hates me, dude!
Johnny Knoxville: You were about five feet short of a ten-foot jump.
Brandon Dicamillo: He penetrated my land as he penetrated my ass, and that is not permitted!
Dave England: I don't mean to toot my own horn, but BEEP BEEP!
Ryan Dunn: I gotta be horrible at everything, otherwise it just wouldn't be me.
Bam Margera: [commenting on his dad with a small Elvis suit on] Oh dude, you like an egg with legs.
Johnny Knoxville: There's no such thing as a pretty good gator wrestler.
Ryan Dunn: I'm Ryan Dunn, and I'm surrounded by morons.
Interviewer: What does the smoke do?
Norm the Beekeeper: Well, the smoke disorganizes and confuses the bees.
Interviewer: Now, if we were to blow the smoke on Mr. Knoxville, would it confuse him?
Scott Potasnik: You guys are gonna hate me an hour from now.
Johnny Knoxville: We hate you already.
Johnny Knoxville: [while duck hunting] We killed Quack Quack!
Johnny Knoxville: [standing in the middle of the road] Hi, I'm Johnny Knoxville and I'm about to get hit by a car real soon!

Johnny Knoxville: [to a cow] Hi sweetie, I'm gonna inseminate you artificially... maybe for real if you play your cards right.
Chris Pontius: Ever since puberty, I've dreamed of being a centerfold in 'Playgirl'.
Chris Pontius: You like this song? Kinda makes you feel like partying. I kinda feel like partying right now.
[tears his clothes away and dances]
Brandon Dicamillo: And today, good sirs, I will stick my lance far beyond where the light of our world shines, deep into the colon of our enemy. Sir Bam-a-lot, you will feel a lot of my lance in your ass.
Chris Pontius: From my experiments with sexiness, it seems like a lot of people are afraid at first, and fear usually equals violence. But eventually I'll win their hearts, and instead of fighting, they'll want to make love to me.
Johnny Knoxville: Even the men?
Chris Pontius: Yep.
Johnny Knoxville: [while getting doused with red wine] Now I know what it feel like to be my liver!
