It first appeared on the third episode of Monty Python's Flying Circus, "How to Recognise Different Types of Trees From Quite a Long Way Away", on BBC1 on 19 October 1969. The romantic background music in the original version of the sketch from the television series is "Charmaine" in the version of Mantovani & His Orchestra, while the film version uses the "Liebestod" from Richard Wagner's Tristan und Isolde.
The sketch starts with a milkman (Michael Palin) delivering milk to a suburban house. The door opens and a seductive woman (Thelma Taylor in the Television version, Carol Cleveland in the film version) steps out and lures the milkman in; the milkman looks around, then enters the house. The woman takes the milkman upstairs, smiling at him and beckoning him with her finger. The milkman cautiously follows her as she unlocks her bedroom door. She opens the door and ushers the milkman inside. As the milkman enters the room, she shuts the door and locks it. The milkman looks around the room and sees several milkmen, some of whom are very old, including one who is a skeleton.
