 "Fibber McGee and Molly" originated when the small-time husband-and-wife vaudevillians began their third year as Chicago-area radio performers.Two of the shows they did for station WENR beginning in 1927, both written by Harry Lawrence, bore traces of what was to come and rank as one of the earliest forms of situation comedy.In their "Luke and Mirandy" farm-report program, Jim played a farmer who was given to tall tales and face-saving lies for comic effect.
