Referring to Simpson's role on MTV's "Newlyweds," Bush told the audience, "Jessica Simpson is here with us, which means we've finally introduced reality TV to the Lincoln Theater."

He meant Ford's Theatre, of course, but everyone knows President Lincoln was shot there. "An easy mistake to make," Senate Minority Leader Tom Daschle told us at a post-show dinner at the Organization of American States.
