Matt is set up on a blind date for the prom, and finds out she is considered the school tramp. Mary and Lucy have dates for the prom but it turns out disastrous.

Three months later, Annie is visibly pregnant and shamelessly complains, and acts as a tyrant to everyone, especially Eric, except for Ruthie who sympathizes with her pregnancy. Matt has given up on going to an out of state college, but not on moving out, so he accepts an invitation to become three girls' roommate, only to be blamed and expelled for their inability to resist his passive male charms. Lucy wins Mary's dare by snapping up an amazingly mature-built 17 year-old named Jordan. Eric's endless misery trying to follow Annie's inconsistent whims and finding an appropriate wedding anniversary gift seems endless, until the gynecological examination yields news that staggers everyone.
