Trevor the Gross

Trevor the Gross is hired as a substitute for Gonzo the Great, when Gonzo plans to leave The Muppet Show in Episode 411 to become a movie star in Bombay. Gonzo spies on Trevor as he flirts with Camilla the Chicken -- but it's the last straw when Trevor steals Gonzo's act, singing "Top Hat" as he tap dances in a vat of oatmeal. Gonzo rushes onto the stage to ask for his job back, and Trevor is fired.
