When David Letterman first moved to Los Angeles he knew little about big-time television. He wanted to break in as an on-screen personality but was unable to find much work until 1976 when the legendary agent/producer Jack Rollins took him on as a client. One of the gigs Rollins set him up with was as the host of an ill-fated game show called The Riddlers in 1977. Aging game show veteran Bob Stewart produced the program and later would be assigned by NBC's Fred Silverman to take charge of Letterman's legendary morning program in 1979-80. However, Letterman did not care to have a game show man producing his new comedy talk show. Stewart ended up being fired four days before The David Letterman Show debuted. Here's the pilot of The Riddlers in its entirety featuring a mostly typical line-up of celebrity panelists and their unlikely host.
