Sherry Dempsey (Marsha Mason) is a waitress at McGinty's, Martin's favorite bar, and, for a short time, Martin's girlfriend. Sherry is fun-loving, brash, loud and crass, and she and Martin share many interests. Frasier and Niles dislike her, but nevertheless, for the sake of family unity, they attempt to tolerate her. When they met her for the first time, it was heard that one of the Crane brothers said: "I didn't know Mae West had a daughter!". Martin and Sherry eventually break up when they decide that they both want different things out of the relationship. (Martin wants to marry, but Sherry wants to keep the relationship at a minor level.)
