One of the most endlessly quotable movies I know is Snatch. Endlessly quotable, I say.
Errol: Are you Turkish?
Turkish: Well I'm not fuckin' Greek now, am I?
Bullet Tooth Tony: A bookie's got blagged last night.
Avi: Blagged? Speak English to me, Tony. I thought this country spawned the fucking language, and so far nobody seems to speak it.
Vinny: What the fuck do you mean, replicas?
Sol: They look the shit, don't they? And nobody is gonna argue. And I've got some extra loud blanks, just in case.
Vinny: In... Oh, in case we have to deafen them to death?
Brick Top: What do you think, Errol?
Errol: I think we should drip-dry them, Guv'nor, while we have the chance.
Brick Top: It was a rhetorical question, Errol. What have I told you about thinking?
Errol: Fuckface, who's speaking to you? He asked him, didn't he?
Turkish: Fuckface... I like that one Errol. I'll have to remember that one next time I'm climbing off yer mum.
Seriously, I could quote that movie all fuckin' day.
