President Bush's response:
"So what if the guy threw his shoe at me?" Bush told a reporter in response to a question about the incident."Let me talk about the guy throwing his shoe. It's one way to gain attention. It's like going to a political rally and having people yell at you. It's like driving down the street and having people not gesturing with all five fingers. It's a way for people to draw attention. I don't know what the guy's cause is. But one thing is for certain. He caused you to ask me a question about it. I didn't feel the least bit threatened by it."See the link above for video and photos. Notice the President's quick reflexes. Quite impressive!
UPDATE: A Saudi man has offered $10,000,000 for the shoe.
UPDATE 2: I'll be just as surprised as you if I'm the first person to make this joke.
