I'm charged with selecting an episode of Freaks and Geeks to show at a fund raiser for Radical Reference.

I've got it down to:
Tests and Breasts, with its academic cheating theme, not to mention adolescent boys dealing with porn
The Diary, for its focus on privacy
Looks and Books, cuz it's geekarrific, with our heroine forced to confront her competitive mathleticism

Which would you pick, and why?
