Furious George

Furious George is Mr. Burns' pet monkey. When Homer borrows Mr. Burns' yacht, Furious George is on board and ends up being engaged in a monkey-knife fight after the yacht enters international waters. Due to Furious George's abilities with a knife, and the scar on his chest, he is presumably trained to knife-fight. The winner of the knife-fight is unclear, although Furious George did sustain injuries.
