Ned Schneebly: I'm not paying your share of the rent. I don't know...maybe you should sell one of your guitars or something.

Dewey Finn: What? Would you tell Picasso to sell his guitars?

Dewey Finn: This school is tough, it will challenge your brain, your mind, and your head.

Dewey Finn: [raising his first three fingers] Read between the lines!

Dewey Finn: God of Rock, thank you for this chance to kick ass. We are your humble servants. Please give us the power to blow people's minds with our high voltage rock. In your name we pray. Amen.

Dewey Finn: Your kids have all really touched me, and I'm pretty sure that I've touched them.

Dewey: Billy what makes you angrier than anything in the world?

Billy: You.

Dewey: Billy, we've already told me off, now let's move on.

Billy: You're tacky and I hate you.

Dewey: Ok, you see me after class!
