The Simpsons Episode 8.03 The Homer They Fall

Homer becomes a boxer and Moe serves as his manager. Even though Homer doesn't have any combinations or footwork to speak of, he can withstand even the most powerful blows to his head and remain standing. Homer fights his way up through the professional ranks and soon agrees to fight a client of Lucius Sweet, a flamboyant boxing promoter with upstanding hair and a taste for flashy jewelry. Drederick Tatum, the boxer Homer is to fight, is the Heavyweight Champ, who will without a doubt pound Homer into a bloody pulp. Marge begs Moe to save Homer if the fight gets too rough, but whether or not Moe has the presence of mind to do so is up in the air.
