In this week's installment of My First Obsession, Fuse tracked down some of metal's biggest acts to find out what these hardcore musicians' childhood passions were—and a few were rather, um, unexpected.
Anthrax bassist Frank Bello admitted that he had a serious thing for Mary Tyler Moore, who was "so hot even back then."
