This hilarious collection of live sketches marks Chevy Chase's feature picture debut. The Groove Tube, directed by Ken Shapiro and starring Chase, Richard Belzer, and others, parodies TV Land and its trappings by spoofing children's television programs, from a pot-smoking Koko the Clown who lives in Make Believe Land to Safety Sam, the penis with a plan who informs the audience of the dangers of casual sex.
