In the iddle of an answer, Bush was getting heated up, starting to shout. Suddeny he stumbled, looked down like he was listening to something, and completely changed the pace, smiled a little…

I think he has an earpiece! Someone told him to calm down!

Update After Kerry answered the last question, the camera was showing both of them. As soon as Kerry finished and before it was Bush’s time Bush cocked his head to listen to something, then gave an answer.

Update – Remember, Bush DOESN’T KNOW that he’s on camera! It’s against the rules, but the networks are doing it anyway.
