Eli (introducing himself to the class): I guess, if nothing else, I'm here to teach you to find the truth in the media. Because there is a difference between what they say and what is real.
Jonathan: Very good. Watch this. Hunter, what did he just say?
Shawn: Something about Israel?
Shawn: The longer you can go without saying those words, the more power you hold. It's in books, man.

Shawn: Men are from Mars, Women Want to Blow Mars Out of the Stinking Sky.

Shawn: Thinking cramp?
Shawn: I get those too.
Cory: Look, all I know is you and I belong together. I mean, I've always been able to talk to you, to make you laugh, and I've always, always wanted to take care of you.
