George W. Bush, standup comedian:
Bush put on a slide show, calling it the "White House Election-Year Album" at the Radio and Television Correspondents' Association 60th annual dinner, showing himself and his staff in some decidedly unflattering poses.
There was Bush looking under furniture in a fruitless, frustrating search. "Those weapons of mass destruction have got to be somewhere," he said.
Because leading your country to war under false pretenses is hiiiiii-larious. (Via Drudge.)
