This is where Cheryl Ladd does her first "full on" Stan Laurel impression, in the office, after Charlie's intercom tells her what her undercover job entails. (She does the mouth/chin expression while scratching the top of her head.) The other title where she goes full on Stan Laurel is Antique Angels, where she even states (to the bad guys) that she's doing the impression.
Director Georg Stanford Brown had previously co-starred (as Terry Webster) in The Rookies (1972) with Kate Jackson (as Jill Danko).
The title is a play on the phrase commonly used to indicate the end of a tennis match, after the final point has been scored: "Game, set, match."
Lee Terri (Mrs. Hailey) later appeared as different characters in season three's Angel on High (1978), season four's Three for the Money (1980), and season five's He Married an Angel (1981).
