Not a line, exactly, but funny all the same! From Monty Python & The Holy Grail:
Sir Lancelot: We were in the nick of time. You were in great peril.
Sir Galahad: I don't think I was.
Sir Lancelot: Yes, you were. You were in terrible peril.
Sir Galahad: Look, let me go back in there and face the peril.
Sir Lancelot: No, it's too perilous.
Sir Galahad: Look, it's my duty as a knight to sample as much peril as I can.
Sir Lancelot: No, we've got to find the Holy Grail. Come on.
Sir Galahad: Oh, let me have just a little bit of peril?
Sir Lancelot: No. It's unhealthy.
Sir Galahad: I bet you're gay.
Sir Lancelot: Am not.
I think you're all fucked in the head. We're ten hours from the fucking fun park and you want to bail out. Well I'll tell you something. This is no longer a vacation. It's a quest. It's a quest for fun. I'm gonna have fun and you're gonna have fun. We're all gonna have so much fucking fun we'll need plastic surgeory to remove our godamn smiles. You'll be whistling 'Zip-A-Dee Doo-Dah' out of you're assholes!
Christal Allen From "The Women":
There is a name for you, ladies, but it isn't used in high society... outside of a kennel.
Lloyd Dobbler from "Say Anything":
I don't want to sell anything, buy anything, or process anything as a career. I don't want to sell anything bought or processed, or buy anything sold or processed, or process anything sold, bought, or processed, or repair anything sold, bought, or processed. You know, as a career, I don't want to do that.
And from "Office Space" the last line in this exchange between Samir and Michael Bolton (not THE Michael Bolton):
Samir: No one in this country can ever pronounce my name right. It's not that hard: Samir Na-gheen-an-a-jar. Nagheenanajar.
Michael Bolton: Yeah, well at least your name isn't Michael Bolton.
Samir: You know there's nothing wrong with that name.
Michael Bolton: There was nothing wrong with it... until I was about 12 years old and that no-talent ass clown became famous and started winning Grammys.
Samir: Hmm... well why don't you just go by Mike instead of Michael?
Michael Bolton: No way. Why should I change? He's the one who sucks.
