#20: One of the Boys (1982)
This sitcom, starring Mickey Rooney, Dana Carvey, and Nathan Lane, aired on NBC in 1982. It followed an old man who moved out of his retirement home to live in a college dorm with his young grandson and friends. It sounds like a cute and promising premise for a sitcom, but it ended up being a flop and was taken off the air after one season.
