I'l spoiler this one, because I need to describe a bit of the context around the scene, and it's a bit of a spoiler.
Brazil Sam has just altered the official records, so that Jill has officially been recorded as dead. He then returns home to find the very much alive Jill in his bedroom, tells her that she is dead and explains what he has done. her response:
"Care for a little necrophilia?"
I just about fell out of my chair laughing at the general wrong-ness of that line.
Vinny Gambini - Joe Pesci Mona Lisa Vito - Marisa Tomei
Vinny Gambini: Hey Stan, you're in Ala-Fuckin-Bama. You come from New York. You killed a good old boy. There is no way this is not going to trial.
and
Vinny Gambini:What about these pants I got on? You think they're okay? Mona Lisa Vito: Imagine you're a deer. You're prancing along. You get thirsty. You spot a little brook. You put your little deer lips down to the cool, clear water - BAM. A fuckin' bullet rips off part of your head. Your brains are lying on the ground in little bloody pieces. Now I ask ya, would you give a fuck what kind of pants the son-of-a-bitch who shot you was wearing?
and
Vinny Gambini: Nothing. You stick out like a sore thumb around here. Mona Lisa Vito: Me? What about you? Vinny Gambini: I fit in better than you. At least I'm wearing cowboy boots. Mona Lisa Vito: Oh yeah, you blend.
and
Vinny Gambini: It is possible that the two yutes... Judge Chamberlain Haller: ...Ah, the two what? Uh... uh, what was that word? Vinny Gambini: Uh... what word? Judge Chamberlain Haller: Two what? Vinny Gambini: What? Judge Chamberlain Haller: Uh... did you say 'yutes'? Vinny Gambini: Yeah, two yutes. Judge Chamberlain Haller: What is a yute? Vinny Gambini: Oh, excuse me, your honor... Vinny Gambini: Two YOUTHS.
So many movies...but I always loved this series from Sorority Boys. One of the main male characters who was dressing up as a woman was drugged and couldn't remember what happened the night before:
Adam/Adina: [noticing a sticky substance on the seat of his skirt] Ah. That's weird. "Roberta": What the hell is on your skirt, man? Adam/Adina: Uh... gum, or something. "Roberta": Oh yeah, what flavor was it? Big fat juicy cock?
Steel Magnolias is a treasure trove of material for a thread like this. A couple of my many favorites from that film:
Clairee Belcher:Well, you know what they say: if you don't have anything nice to say about anybody, come sit by me!
-and-
Drum:Ouiser, can we call a truce long enough for me to get a piece of cake? [Ouiser slices him the tail piece of the groom's armadillo-shaped cake] Drum:Aww, thanks Ouiser. Nothin' like a good piece of ass.
This one from David Wayne in "Adam's Rib" always makes me laugh:
"Lawyers should never marry other lawyers. This is called in-breeding; from this comes idiot children... and other lawyers."
From Tommy Boy:
"Tommy:You know a lot of people go to college for seven years. Richard: I know, they're called 'doctors'."
From "Better Off Dead":
"Gee, I'm real sorry your mom blew up, Ricky."
From "Miller's Crossing"
"Hitman: If I tell you, how do I know you won't kill me? Eddie Dane: Because if you told me and I killed you and you were lying I wouldn't get to kill you then"
From "The Quiet Man"
"He'll regret it till his dying day. If ever he lives that long"
Happy Gilmore- Shooter McGavin: "I eat pieces of shit like you for breakfast." Happy Gilmore: (Laughing)"You eat pieces of shit for breakfast?" Shooter McGavin: ".....NO!"
Billy Madison- Crazy Janitor: "Billy, likes to drink soda. Miss Lippy's car....is green."
Bearded Lady: Hey, baby. You ever had a chick with a beard before? Mitch: Can't say that I have there, bearded broad. Bearded Lady: Well, then, sugar, you haven't lived. Mitch: Note to self: I don't want to live.
