Boston Public - Season 1 Episode 12

As Senate approaches the school grounds, he saves a student from being attacked by gang members. After numerous attempts, Harry finally manages to get the boy to reveal that he is a member of the Crips. Meanwhile, Harper grows even more suspicious about Lisa and Buttle's deepening friendship, so Guber takes the reins and alerts Lisa's parents about their daughter's rumored affair. In the midst of these crises, Lauren has her hands full trying to help an overweight female wrestler, Christine, cope with the loss of her boyfriend. After winning an important wrestling match, Christine addresses the audience and asks them to stop calling her "The Blob", even when it's supportive. They respond by chanting her name instead. Lisa Grier's father goes to Buttle's home and catches them about to have sex. The next morning, Guber gives Buttle a choice: Voluntarily resign or be fired in such a manner as he'll never teach again. Buttle resigns and is ordered to leave by Guber. Harper also rebuffs Buttle. Kevin Riley talk to Guber and tries to mitigate Buttle's actions and ends up getting fired immediately for not disclosing the affair sooner.
