14. Condoleezza Rice, on attacks on U.S. soil
Got an American history question? You might want to think twice before making Condoleezza Rice your go-to girl. She might be one of the most accomplished ladies in the nation, but even she, like Herman Cain, is capable of the occasional (unforgettable) brain fart. In the midst of a 9/11 discussion with David Letterman on his late night talk show, the former Secretary of State asserted:
"Well, we had not been attacked on our territory since the War of 1812, when the British burned the White House."
Uh, does Pearl Harbor not count?
