“Get your hands off me you damn dirty ape!”
What a great verb! What’s its past tense?
Seriously, though:
rather adverb 1. (often foll. by than) by preference; for choice (would rather not go; would rather stay than go). (Canadian Oxford Dictionary).
Don’t feel bad. Someone else once tried to correct me on grammar and syntax too.
:dubious: As you say.
Actually, I think **matt_mcl ** is right and I’m wrong. I’m sure it was just a luck guess on his part, though 
Nothing can touch Blackadder:
This isn’t an insult, but it is a beautiful smackdown. Consider my ignorance fought, too–I was thinking you were wrong. They’re gonna take away my grammarnazi card for this, I tell you.

I still love the insult in *Napoleon Dynamite * :
“Your mother goes to college”.
It is just so beautifully random.
I like Affleck and Damon’s exchange with each other in Jay and Silent Bob Strikes Back right before filming Good Will Hunting 2:
Matt Damon: Just take it from “It’s a good course.”
Ben Affleck: Oh, now you’re the director.
Matt Damon: Hey shove it, Bounce-boy. Let’s remember who talked who into doing this shit in the first place. Talking me into Dogma was one thing, but this…
Ben Affleck: Hey look, I’m sorry I dragged you away from whatever-gay-serial-killers-who-ride-horses-and-like-to-play-golf-touchy-feely-picture you’re supposed to be doing this week.
Matt Damon: I take it you haven’t seen Forces of Nature?
Ben Affleck: You’re like a child. What’ve I been telling you? You gotta do the safe picture. Then you can do the art picture. But then sometimes you gotta do the payback picture because your friend says you owe him.
[They both take a beat and look at the camera]
Ben Affleck: And sometimes, you have to go back to the well.
Matt Damon: And sometimes, you do Reindeer Games.
From Casablanca:
Major Strasser: “Those Americans are mere blunderers.”
Capt. Reynaud: “Oh, I don’t know. I was with them when they blundered into Berlin in 1918.”
I know, I know; American troops never reached Berlin during WWI.
Aha! A prescriptivist! 
Hey, I know this is supposed to be an insult thread, but that’s just nasty!
how about…“I’d rather be his whore than your wife.”-Titanic
How about this, Askance?
I just saw Steel Magnolias again and I think I will adopt
“You’re a pig from hell!”
From the no-budget but hysterically funny (well, to me- ymmv) drag movie Girls Will Be Girls:
Evie (washed up 70s TV star and general nightmare of a person) says of new “hefty” roommate Varla “a little less binge and a little more purge, just saying” during a fight. Then later:
Coco: Evie, Varla said she was sorry for what she did…
Evie: I heard her.
Coco: Well, don’t you think you said some things you could apologize for?
Evie: Like what?
Coco: You said she was all binge and no purge.
Evie: I did?
[laughs]
Evie: That’s funny!
(Must be seen to be fully appreciated; you have to respect a movie that has exchanges such as the following-
Evie (wondering why the public turned against her): Then what is it?
Stevie: You know what it is… that family of four that you ran down when you were driving drunk.
Evie: It was a family of six! I only killed four… and who has a picnic in their own back yard?
or, when asked if she’s ever had an abortion:
Evie: Coco, I’ve had more children pulled out of me than a burning orphanage.)
Blackadder again:
A thread about great tv insults and noones mentioned red dwarf.
“I have hair like yours, just not on my head”
“You’re about as useful as a condom machine in the Vatican”
LISTER: But Rimmer, he asked for you. He obviously feels some sort of bond.
RIMMER: The only ‘bonding’ I want to do with him involves a tube of superglue and a rabid hamster!
More Blackadder: (from memory)
SIR TALBOT BUXOMLEY: I care not that you are the son of a certifiable sauerkraut-sucking loon! It is no skin off my rosy nose that there are bits of lemon peel floating down the Thames better suited to be Regent than you! Regent you are, appointed by God, and I will stand by you though illness and ill health afflict me!
PRINCE GEORGE: Good on you!
Time 4:13 by that consummate actor, Daffy Duck.
IIRC Otto had some sort of complex which made him extraordinarily sensitive to being thought of as stupid, the context of which makes this exchange even funnier and a real turning point in the movie, after people have been humoring him.
