Episode: “The Fire” (Season 5, Episode 19)

Favreau has been a fixture in Hollywood for upwards of 30 years. Starting with Swingers, Favreau first became an actor — and has since become heavily involved in directing. On Seinfeld, he played Eric the Clown — a character hired to entertain the son of George Costanza’s girlfriend. In typical Seinfeld fashion, Eric and George got into a fight.
