Anyone like Me, Myself, and Irene? There's a ton of wicked quotes in that movie.
Jamaal, "Our daddy may have advanced delusionary schizophrenia with involuntary narcissistic rage. But he is a very gentle person!"

After I guy throws his cig infront of Hank.
Hank Evans: Hey ringworm...
[Softball Player looks around]
Hank Evans: Yeah I'm talking to you, you toxic waste of life. You gonna pick that butt up, or do I have to glue it to the end of my shoe and stick it in your big fat pimply a-hole?
Softball Player: Hey buddy, chill out. It's just a cigarette.
Hank Evans: Oh yeah? Well this is just a fist. But when I start throwing it around I can leave one hell of a mess.

Shonte Jr.: Anybody know how to fly this damn thing?
Jamaal: Motherfucker, it can't be that hard, it's just lift versus drag and rotation.
Lee Harvey: Yeah, man, get your head out your ass.
Shonte Jr.: It's not that, man, the controls are written in German, ya asshole.
Lee Harvey: Motherfucker, you speak German don't you?
Shonte Jr.: Motherfucker, I can speak it, I ain't saying I can read the shit all that good.
Jamaal: [Grabs instruction book] You a motherfuckin' disgrace!

Shonte Jr.: Okay so I add up the atomic masses of the proton and neutron, I see's that, but what do I do with the goddam electron? Can I bring it over here?
Jamaal: Enrico Fermi would roll over in his motherfucking grave if he heard that stupid shit. I mean he would just turn over ass up in your face and wouldn't give a fuck!

I love the 3 black kids in that movie... one of my favs. Sorry for the long ass post.

Here's a few more:

Hank Evans: You know, I think you're a very special unit.
Irene P. Waters: That's sweet.
Hank Evans: I hope we get to know each other better.
Irene P. Waters: Yeah, me too.
Hank Evans: Do you swallow?

Irene P. Waters: Stay away from me, Hank! I know what you have planned, OK? I saw your so-called "supplies."
Hank Evans: Oh... that! I wasn't gonna just... ram it home, you know. I was gonna... lube it up and ease it in there, inch by inch, like a gentleman.
Irene P. Waters: I was talking about the shovel and the lime.

Guy on Street: Hey big guy, you hear the news, my son Billy got the lead in his school musical.
Hank Evans: Well I guess he likes the cock after all.
