First Aired: August 22, 2001
Plot: The quiet of Quahog is disrupted when the leaves start turning fall colors and “leafers” from New York City invade town. Bonnie invites Lois to a Tae Jitsu class where Lois quickly advances to black belt. Peter almost gets into a fight with a new yorker, but Lois beats him up instead to keep Peter out of trouble. Lois and Brian think Peter is embarrassed, but Peter changes his mind, and exploits Lois’s fighting abilities to drive the leafers back to New York. Peter takes advantage of this to a great level, but Lois begins to get out of control. She even attacks her karate sensei. In one occurrence in a scene Lois rapes Peter.
Stewie walks in on Peter eating his Gram Crackers, and gets very angry. Peter tells Brian what Lois did, but when Stewie strikes Peter with a baseball bat, Lois resolves to rid the house of anger. She takes Stewie to a child's anger managment class, but Stewie attacks the psychiatrist. Soon Lois gets into an argument with Peter, but Brian tries to convince them by giving them supposed mood elevating drugs but it ends up that he lied and gave them placebos. Peter and Lois argue again, then they get into a fight. Peter surprisingly manages to be evenly matched with Lois, so Chris cheers him on. Meg gets angry with Chris because Peter was the one who took advantage of Lois, but Chris counters by reminding her that Lois went out of control. Meg pokes Chris in anger, and Chris attacks her, saying he doesn't like to be touched. Stewie and Brian then begin to fight for no reason. The family ends up in an all-out brawl. They fight viciously, destroying everything in the house. But they begin to laugh when they realize how ridiculous this all is. The laughter is cut short when Stewie hits Lois with a chair. Finally exhausted, with broken bones and a ruined house, they blame the violence on TV. Peter then blames the network, FOX, and the shows budget is cut short as revenge.
