Notes: The woman in Monty Python and the Meaning of Life who chase a man off the cliff to his death while topless are dressed like Roller Derby performers but don't appear to be wearing any actual rollerskates, I am going to assume they were meant to since you never see their feet they just didn't want any of the women to injure themselves.
