Francis: Morning Pee-wee.
Pee-wee: Hello Francis
Francis: Today's my birthday, and my father said I can have anything I want.
Pee-wee: Good for you and your father.
Francis: So guess what I want.
Pee-wee: A new brain!
Francis: No. Your bike.
Pee-wee: Ha ha! HA HA HA! Ha Ha Ha! (Rolling On Ground In Laughter)
Francis: Oh what's so funny, Pee-wee?
Pee-wee: It's not for sale, FRANC-IS!
Francis: My father says everythings negotiable, PEE-WEE! (brandishing money)
Pee-wee: I wouldn't sell my bike for all the money in the world. Not for a hundred, billion, million, trillion dollars!
Francis: Then you're crazy!
Pee-wee: I know you are, but what am I?
Francis: You're a nerd!
Pee-wee: I know you are, but what am I?
Francis: You're an idiot!
Pee-wee: I know you are, but what am I?
Francis and Pee-wee: I know YOU are, but what am I? (5 times)
Pee-wee: Infiniti.
PW & Francis: No, I'm not, you are.
PW & Francis: No, why...
PW & Francis: Knock it off.
PW & Francis: Cut it out.
Francis: Oh shut up, Pee-wee!
Pee-wee: Why don't you make me?
Francis: Why don't you make me?
Pee-wee: Because! I don't make monkeys, I just train 'em!
Francis: Oh Pee-wee, listen to reason. (Pee-wee pretends he's listening to something else) Com' on!
Pee-wee: Shhh! I'm listening to reason.
Francis: PEE-WEE!
Pee-wee: That's my name, don't wear it out.
Francis: (desperately) Remember the first time I saw your bike? You were riding past my house and I came running out to tell you how much I liked it even way back then?!
Pee-wee: I love that story. Heheh.
(Pee-wee begins to ride away from Francis)
Francis: YOU'LL BE SORRY, PEE-WEE HERMAN!

My favorite is when P.W. says "I don't make monkeys, I just train 'em!" That was my senior quote in high school. This is also one of the few movie exchanges I have memorized.
