When a rash of burglaries in the neighborhood makes Lucy and Viv feel unsafe, they learn judo for self-protection. The tactic backfires when they teach it to their sons, who use it on one another.

Herman (a mouse) and Henry (a rooster) notice a poster that will award $1,000 to anyone who will stay in the ring for one round against a champion boxing rooster.
