Lillian Müller
In addition to dating Hefner back when he was a young lad of 498, you might recognize 1976 Playmate of the Year Lillian from such boner factories as Van Halen's "Hot for Teacher" video, where she played a particularly brainy chemistry teacher. Muller also starred as Rod Stewart's "Do Ya Think I'm Sexy?" video, reminding us that feathered hair was once considered the height of attractiveness.
