Season 1, Episode 12 - "Hell Week"
18 December, 2001
War breaks out between the guys and Books after Steven quits pledging the Theta frat during Greek Week. In order to stop the madness, the guys steal the Theta letter from the frat, and hold it hostage (and of course, they have some "fun" with it as well). Meanwhile, Lizzie and Tina try to subtly point out to Rachel that she's gained the "Freshman 15," and they end up offending her instead.
