Just stupid. A Montana man who was legally Bob Craft until, in late 1997, he changed his name to Jack Ass is now suing Viacom (parent of MTV) for defamation and wants $10 million in damages. He’s concerned that people will confuse the MTV show and movie of the same name with him and his good works. As if anyone stupid enough to call himself Jack Ass, whatever the reasons, could be defamed.
