Well, here's one that he won't live down any time soon. A contestant on the "$100000 Pyramid" game show managed to confused Barack Obama with Osama bin Laden.
The on air gaffe took place on ABC's Sunday broadcast during the category "People Whose Last Name is Obama."
Calling the mistake "perhaps the most embarrassing moment" of his life, Evan Kaufman answered "Osama" before correcting himself with the former president's name.
Kaufman ended up leaving the game $8,500 richer and a whole lot redder in the face.
What's the worst public mistake you made? How embarrassed were you? Do people still bring it up? Does it still keep you up at night?
