Tube Bar prank calls

The Tube Bar prank calls are a series of prank calls made from 1975 until 1977 or 1978 to the Tube Bar in Jersey City, New Jersey, in which Jim Davidson and John Elmo would ask "Red", the proprietor of the bar, if they could speak to various non-existent customers. The gag names given by the pranksters were puns and homophones for often offensive phrases. Recordings of the calls were circulated widely on duplicated cassette tapes and may have been the inspiration for a long running gag in The Simpsons.
