"Portrait of a TV fan. Name: Joe Britt. Occupation: cab driver. Tonight, Mr. Britt is going to watch 'a really big show,' something special for the cabbie who's seen everything. Joe Britt doesn't know it, but his flag is down and his meter's running and he's in high gear - on his way to the Twilight Zone."
Joe Britt insults the TV repairman. The repairman later tells Joe that he has fixed it for free. Suddenly, the TV picks up a channel Joe's never been able to get. On it he sees himself and his mistress. Then it shows a scene of Joe and his wife arguing, and Joe punching her through a window. Afraid, Joe confesses his misdeed to his wife, they argue, and he ends up punching her through a window to her death."The next time your TV set is on the blink, when you're in the need of a first-rate repairman, may we suggest our own specialist? Factory-trained, prompt, honest, twenty-four-hour service. You won't find him in the phone book, but his office is conveniently located - in the Twilight Zone."
