Metallica guitarist Kirk Hammett is still scarred by the childhood memory of his neighbour having sex with his dog. The rocker was just 11 when stumbled across his pet dog Tippy being penetrated by his next door neighbour. He tells Britain's Q magazine, "The guy took down his pants and started having sex with the dog! I didn't know whether to laugh or cry. "When he got up, I just took the dog and left. She was still wagging her tail."
