Mr. Woodman accuses Gabe of not following standard teaching procedures because he isn't teaching from the standard textbook. The Sweathogs come to his defense in front of the school board.

Gabe is less than thrilled when an old too-perfect classmate, and his too-perfect wife, decide to pay him a visit.

Mr. Kotter talks Judy into tutoring Barbarino. The two eventually become friends, but Barbarino doesn't want the other Sweathogs to know about it.
