OK, Ms DumBum ain't your teacher today, I am, and I have a headache and the runs. So I say, time for recess!Dewey Finn
Dewey Finn: Ok, here's the deal. I have a hangover. Who knows what that means?
Frankie: Doesn't that mean you're drunk?
Dewey Finn: No. It means I was drunk yesterday.
Freddy: It means you're an alcoholic.
Dewey Finn: Wrong.
Freddy: You wouldn't come to work with a hangover unless you were an alcoholic. Dude, you got a disease!
Dewey Finn: Hmmm... hmmm... What's your name?
Freddy: Freddy Jones.
Dewey Finn: Ok, Freddy Jones, shut up!
Dewey Finn: [on sticking it to "The Man"] Yes! But, you can't just say it, man. You've gotta feel it in you're blood and guts! If you wanna rock, you gotta break the rules. You gotta get mad at the man! And right now, I'm the man. That's right, I'm the man, and who's got the guts to tell me off? Huh? Who's gonna tell me off?
Freddy: Shut the hell up, Schneebly!
Dewey Finn: That's it Freddy, that's it! Who can top him?
Alicia: Get outta here, stupidass.
Dewey Finn: Yes, Alicia!
