Turn-On is an American sketch comedy series that aired on ABC in February 1969. Only one episode was shown, leaving one episode unaired, and the show is considered one of the most infamous flops in TV history.
Turn-On's sole episode was shown on Wednesday, February 5, 1969, at 8:30 pm ET. Among the cast were Teresa Graves (who would join the Laugh-In cast that autumn) and longtime children's show host, character actor, and voice artist Chuck McCann. The writing staff included a young Albert Brooks. The guest host for the first episode was Tim Conway.
