Van Halen's 1984 hit single "Hot For Teacher" off their hit album "1984" wasn't just a classic '80s rock hit, but it also was a representation of what goes on in the minds of teenage boys at school. The hit single is also noted for its music video, which featured kids at school going hot for their teacher -- and one of the models who played a teacher was Lillian Muller.
