The Groove Tube (1974)

Chevy Chase makes his film debut in this riotous collection of live skits. Directed by Ken Shapiro and featuring Chase, Richard Belzer and others, The Groove Tube mocks TV Land and its trappings by spoofing kids’ shows — from a marijuana-smoking Koko the Clown who resides in Make Believe Land, to Safety Sam, the penis with a plan who gleefully informs the audience of the perils of casual sex.
