Or pre-emptively reactionary to reactionaries, but I think that Bush's jokes about WMD at the Radio and Television Correspondents' Association 60th annual dinner were inappropriate material and could prove to be a serious political misstep:

There was Bush looking under furniture in a fruitless, frustrating search. "Those weapons of mass destruction have got to be somewhere," he said.

This, on the other hand, was hilarious:

There was Vice President Dick Cheney (news - web sites), a frequent butt of gentle Bush ribbing, holding his fingers a few inches apart. Bush said, "Whenever you ask him a question, he replies, 'Let's see what my little friend says.'"
