Taxi (1978)

Season 4, episode 4

While driving a television executive in his cab, Jim exhibits more psychic behavior by predicting TV ratings. Mitch, the executive, seeks Jim out the next day in hopes of getting more advice about TV programming that might save his job. Jim starts helping Mitch regularly and Mitch becomes a star at the network, but the gang soon convinces Jim (who isn't being compensated for this help) that he's being taken advantage of. Jim angrily confronts Mitch, who agrees to tell the network head honchos all about Jim and to get him a job, but Jim has a change of heart, saying he doesn't want to profit from his God-given gift as a psychic.
