Taxi - Season 3 Episode 6 : The Ten Percent Solution 1983

Bobby is fed up after losing an acting gig to an inferior actor with the right look, which he explains to be like Tony. Tony decides he wants to capitalize on this and give acting a try, and asks Bobby to be his manager. Reluctantly, Bobby agrees and soon, despite a terrible audition, Tony gets a major role in a movie. Bobby is soon regretting his decision to take Tony under his wing, though, since he's resentful that Tony (whose acting is not improving, despite Bobby's coaching) could get a part so easily. Bobby feels vinidicated, however, when Tony is eventually cut from the film because of his lack of skills.
