Jester was in one episode of Gunsmoke, the longest running TV series in history that ran from 1955 to 1975. This cut is from episode 14 from the first season aired in Jan 1956 called, "Professor Lute Bone". Jester plays this Medicine Man's assistant/slave? He plays the banjo and has two lines. I think he fakes the banjo pretty well. . Better than most actors who have to pretend to play an instrument.
