A gal I know who worked at barns and noble often in the music/movies section had an encounter with a customer that I found quite funny. A man came in asking for the mel brooks film history of the world part ONE. The gal told him there is not part one, and that's part of the joke. "I get the joke I just want to see part one now that I've seen part two." She told him three more times and he had the same reaction every time, so she asked a male employee to explain it to him. For some reason it stuck that time.

Murphy would have been steaming. ;)
