Mac: All right, kids, how you feeling?
Ducks' Team: Good.
Mac: Good? Doesn't sound good. Are you drinking the Red Bull? Come on, chug 'em down!
Ducks' Player: I feel sick.
Mac: That's the vitamins ripping out the inside of your stomach. That's a good thing, trust me.

Mac: Do you want to shove heroin into your ass?
Charlie: Dude, I don't want to shove anything in my ass!
Mac: All right! This is the perfect opportunity to prove how hard we are, and not have to shove anything up our asses!

Mac: Well, maybe it boils down to this, smart guy: Computers are for losers.
Dennis: You're drinking a beer at 8:00 in the morning!
Mac: Whatever, dude. Irrelevant.
(Frank has just been informed by his ex-wife Barbara that he is not Dennis and Sweet Dee's father.)

Mac:Charlie look, I normally wouldn't come to you with this sort of thing because you're incredibly unreliable... but Dennis, Dee and Frank are all directly connected to this. Dennis' mom tried to have sex with me!
Charlie: Interesting...
Mac: Yeah man, she got naked... she came on to me. I mean, that woman is straight crazy, but I think I wanna bang her, man! I know I shouldn't do it...
Charlie: I think you should do it!
Mac: What?
Charlie: Look, an opportunity like this only comes around once in a lifetime right?
Mac: Right!
Charlie: And so you'd be a fool to let it slip through your fingers.
Mac: Yeah! That's what I'm thinking! But... it's Dennis and Dee's Mom...
Charlie: Well that means that no one ever ever is going to find out.
Mac: That doesn't make any sense...
Charlie: It doesn't have to make sense!
Mac: You're right! I'm gonna do it!

Waitress: I wrote down my phone number.
Charlie: Wow!
Waitress: Please... please, Charlie, please don't make me regret giving this to you. (The waitress hands a folded piece of paper to Charlie)
Charlie: No absolu... absolutely not. No, this will be a platonic sponsor, sponsoree kind of a thing. (He unfolds the piece of paper) Oh... no shi... I was so close.
