Blond Treehorn Thug: [holding up a bowling ball] What the fuck is this?
The Dude: Obviously you're not a golfer.
Walter Sobchak: Nihilists! Fuck me. I mean, say what you like about the tenets of National Socialism, Dude, at least it's an ethos.
The Dude: Look, just stay away from my fucking lady friend.
Da Fino: Hey, I'm not messing with your special lady.
The Dude: She's not my special lady, she's my fucking lady friend. I'm just helping her conceive.
Walter Sobchak: [shouting] Has the whole world gone crazy? Am I the only one around here who gives a shit about the rules? Mark it zero!
Walter Sobchak: Shut the fuck up, Donny.
The Dude: Fuckin' Quintana... that creep can roll, man.
Walter Sobchak: Yeah, but he's a pervert, Dude.
The Dude: Yeah.
Walter Sobchak: No, he's a sex offender. With a record. He served 6 months in Chino for exposing himself to an eight year old.
The Dude: Oh!
Walter Sobchak: When he moved to Hollywood he had to go door to door to tell everyone he was a pederast.
Donny: What's a... pederast, Walter?
Walter Sobchak: Shut the fuck up, Donny.
Jesus Quintana: What's this day of rest shit? What's this bullshit? I don't fuckin' care! It don't matter to Jesus. But you're not foolin' me, man. You might fool the fucks in the league office, but you don't fool Jesus. This bush league psyche-out stuff. Laughable, man - ha ha! I would have fucked you in the ass Saturday. I fuck you in the ass next Wednesday instead. Wooo! You got a date Wednesday, baby!
Jesus Quintana: You ready to be fucked, man? I see you rolled your way into the semis. Dios mio, man. Liam and me, we're gonna fuck you up.
The Dude: Yeah, well, you know, that's just, like, your opinion, man.
Jesus Quintana: Let me tell you something, pendejo. You pull any of your crazy shit with us, you flash a piece out on the lanes, I'll take it away from you, stick it up your ass and pull the fucking trigger 'til it goes "click."
The Dude: Jesus.
Jesus Quintana: You said it, man. Nobody fucks with the Jesus.
Walter Sobchak: Eight-year-olds, Dude.
Walter Sobchak: Fuck it, Dude, let's go bowling.
And pretty much the rest of the flick, too.
