2. Jack Benny
Eddie Anderson - Rochester Van Jones, Jack's valet and chauffeur. Early in the show's run, he often talked of gambling or going out with women. Later on, he generally complained about his lack of salary
Mary Livingstone - Herself. Although in real life she was Jack Benny's wife, on air (TV or Radio) she only played a friend to Jack. Sometimes she was presented as a date, sometimes as a love interest and sometimes she was just there. Her role changed from plot to plot and she was never a steady girlfriend for Jack.

Mel Blanc - Carmichael the Polar Bear, Professor Pierre LeBlanc, Sy the Mexican, Polly (Jack's parrot), The Maxwell and many other assorted voices. An occasional running gag went along the lines of how the various characters Mel portrayed all looked alike.
Don Wilson - Himself. Don generally opened the show and also did the commercial. He was the target of Jack's jokes, mostly about his weight.
