There were some good ones in The Princess Bride.
Inigo: Hello down there! Slow going?
Roberts: Look, I don't mean to be rude, but this isn't as easy as it looks so I would appreciate it if you wouldn't distract me.
Inigo: Sorry! I don't suppose you could speed things up?
Roberts: Look if you're in such a rush you could lower a rope or a tree branch or find something useful to do.
Inigo: I could do that. I have some rope up here. But I do not think that you will accept my help, as I am only waiting around to kill you!
Roberts: That does put a damper on our relationship.
Inigo: But I promise I won't kill you until after you've reached the top.
Roberts: That's very reassuring, but I'm afraid you'll just have to wait.
Inigo: I hate waiting. Can I give you my word as a Spaniard?
Roberts: No good! I've known too many Spaniards!
Vezzini: He didn't fall? Inconceivable!
Inigo: You keep using that word. I do not think it means what you think it means.
Vezzini: Give her to me! Catch up to us when he's dead!
Fezzik: What do I do?
Vezzini: Finish him! YOUR way!
Fezzik: Oh good! My way! Thank you Vezzini. Which whay's my way?
Vezzini: Pick up one of those rocks. Get behind the boulder. In a few minutes the man in black will be coming around the bend. The moment his HEAD is in sight, HIT IT WITH THE ROCK!
Fezzik: My way's not very sportsmanlike.
Fezzik: I did that on purpose. I don't often miss.
Roberts: I believe you. So what now?
Fezzik: Now we face each other as God intended, sportsmanlike. No weapons. No tricks. Just skill against skill alone.
Roberts: You mean I put down my sword, you put down your rock, and we try and kill each other like civilized people.
Fezzik: Or I could kill you now.
Roberts: I think the odds are slightly in your favor when it comes to hand fighting.
Fezzik: It's not my fault for being the biggest and the strongest. I don't even exercize.
Roberts: Are you just fiddling around with me or what?
Fezzik: I just want you to feel you're doing well. I hate for small people to die embarassed.
Inigo: Are you the Miracle Max who worked for the king all those years?
Max: The king's stinkin" son fired me! And thank you so much for bringing up such a painful subject. Next time why don't you just give me a nice paper cut and pour lemon juice on it? We're closed!
(Closes the window & Inigo keeps knocking)
Beat it or I'll call the brute squad!
Fezzik: I'm on the brute squad.
Max: You ARE the brute squad.
Inigo: He's dead, he can't talk.
Max: Oh-ho, look who knows so much. Well it just so happens that your friend here is just mostly dead. There's a big difference between mostly dead and all dead. Mostly dead is slightly alive. All dead, well with all dead there's pretty much just one thing you can do.
Inigo: What's that?
Max: Go through his pockets and look for loose change.
Humperdinck: To the death!
Wesley: No! To the pain!
Humperdinck: I don't believe I'm familiar with that expression.
Wesley: I'll explain. And I'll use small words so you'll be sure to understand, you worthog faced buffoon.
Humperdinck: I do believe that is the first time anyone has ever dared to insult me.
Wesley: It won't be the last.
