Taxi - Season 3 Episode 17
Bobby and the Critic

Bobby, who is appearing in a one man play, is fired up about a ruthless theater critic who has been writing scathing reviews. Bobby writes an angry letter to the critic, but throws it away without sending it, having already felt better for venting his anger. Predictably, Louie fishes it out of the trash and mails it, and it gets printed in the newspaper. Bobby is soon getting cheers from actors all over the city, but gets worried when he learns that the critic himself is going to be at Bobbys play. After the play, the critic finds Bobby and hands him a wonderful review of his performance. Bobby is overcome until the critic says hes not going to print it, because rather than a scathing review which would seem like sour grapes or a good review that would boost his career, not submitting a review will leave Bobby in obscurity and the critic will have his vengeance.
