Wendy Dio says she considers an effort by Gene Simmons of KISS fame to obtain a trademark on the 'horn's gesture (demonstrated by Lars Ulrich of Metallica) both 'laughable' and 'disgusting'.  Her late husband Ronnie Jame Dio had as much or more to do with its adoption by Rock fans as anyone. Ronnie, who maintained the gesture was something his grandmother used to flash, once quipped when the gesture was brought up in an interview, 'Gene Simmons will tell you that he invented it. But then again, Gene invented breathing and shoes and everything else.'
