Dewey: Oh, you wanna learn something?
Summer: Yes, I do.
Dewey: You want me to teach you something? [most of the students nod]Here's a useful lesson for you: give up. Just quit. Because in this life, you can't win. Sure, you can try. [really getting angry] But in the end you're just gonna lose, BIG TIME. Because THE WORLD is run by the Man.
Frankie: Who?
Dewey: The Man. Oh, you don't know the Man? [class shakes their heads] He's everywhere. In the White House, down the hall, MISS MULLINS, she's the Man. And the Man ruined the ozone, and he's burning down the Amazon, and he kidnapped Shamu and put her in a chlorine tank! Okay? And there used to be a way to stick it to The Man. It was called rock ‘n’ roll. But guess what. Oh, no. The Man ruined that too with a little thing called MTV! So don’t waste your time trying to make anything cool or pure or awesome, because The Man’s just going to call you a fat, washed up loser and crush your soul. So do yourselves a favor and just GIVE UP!!!
