Ozzy Osbourne's visit to the White House this weekend appeared to be a success, reports Reuters. The former lead singer of Black Sabbath earned wild cheers from the crowd during the 88th annual dinner of the White House Correspondents Association. The rocker nearly upstaged President George W. Bush when he stood on his chair to wave to the adoring fans. But the president showed off his sense of humor by quipping, "Ozzy... might have been a mistake." According to The Drudge Report, Vice President Dick Cheney's wife Lynne was heard to complain: "He's hardly someone we should be applauding... not a role model. I am rather embarrassed."
