Hayden Rorke also played a doctor in the 1960's sitcom "I Dream Of Jeannie".
Lt. Ives (Jack Ging), Lt. Malcolm (Ward Wood) and Lt. Tobias (Robert Reed) all appear on camera in this episode.
When Stella plays a music cassette the music starts as soon as she lowers the lid on the player. Most (if not all) cassette players need the play button to be pushed before the playing head is engaged and the motor is started to turn the reels of tape against the head.
When Joe enters Georgia's topless restaurant, the letters in the "GIRLS" sign (which the camera zooms in on) has evenly spaced letters. The 'R' appears to have tape on it to hold it up. When Joe leaves the restaurant the 'R' has slipped and is now lower and to the right of where it was before.
Although this episode was filmed for the 1973-74 season and aired in September 1973 the calendar outside Ferarro's office shows January 1972 - almost 2 years earlier.
