"I know what you're thinking. Did he fire six shots or only five? Well, to tell you the truth, in all this excitement, I've kinda lost track myself. But being as this is a .44 Magnum, the most powerful handgun in the world, and would blow your head clean off, you've got to ask yourself one question: 'Do I feel lucky?' Well, do ya punk?" (Dirty Harry)
"klaatu barada nikto" (the day the earth stood still)
"nobody's perfect!" (some like it hot)
"bonjour" (le dernier combat, the only word spoken in the entire film)
"...Bond. James Bond" (any of 'em)
"I'm not even supposed to be here today!" (Clerks)
and finally, my current favourites

:
A: "Hey we gotta find ourselves a Smurfette."
B: "Smurfette?"
A: "Mm-hmm. Not some like, tight-ass Middlesex chick, ya know? But this cute little blonde that'll get down 'n' dirty with the guys, like Smurfette does."
Donnie: "Smurfette doesn't f**k."
A: "That's bullshit. Smurfette f**ks all the other smurfs. Why do you think Papa Smurf made her? Because all the other smurfs were getting too horny."
B: "No, not Vanity. I heard he was a homosexual."
A: "Okay, well you know what? Then she f**ks them while Vanity watches. Okay?"
B: "But what about Papa Smurf? I mean, he must get in on some of the action."
A: "Yeah, what he does... He films the gang-bang, and later on he beats off to the tape."
Donnie: "First of all, Papa Smurf didn't create Smurfette; Gargamel did. She was sent in as Gargamel's evil spy with the intention of destroying the smurf village. But the overwhelming goodness of the smurf way of life transformed her. And as for the whole gang-bang scenario, well hey. It just couldn't happen! Smurfs are asexual; they don't even have reproductive organs under those little white pants. It's just so illogical, ya know, about being a smurf. I mean, what's the point of living if you don't have a dick?"

Donnie: Why do you wear that stupid rabbit suit?
Frank: Why do you wear that stupid man suit?
