Continuity mistake: Coach Brakett (Boyd Gaines) finally convinces the young gym teacher, Honeywell (Kim Cattrall), to go with him to the boys' locker room. Once they are up there he disrobes her and gets on top of her. When they cut to a close-up, you can tell that he has longer hair than just two seconds before. (00:58:40 - 00:59:40)
Wendy: Has anybody seen Mike Hunt?
Meat: Practically everybody in town from what I hear.
