Recently while going through an airport during one of his many trips, President George W. Bush encountered a man with long hair, wearing a white robe and sandals, holding a staff. President Bush went up to the man and said, "Aren't you Moses?" The man never answered but just kept staring straight ahead. Again the President said, "Moses!" in a loud voice. The man just kept staring ahead, never answering the President. Bush pulled a Secret Service agent aside and pointing to the robed man asked him, "Doesn't that man look like Moses to you?" The Secret Service agent agreed. "Well," said the President, "every time I say his name, he just keeps staring straight ahead and refuses to speak. Watch!" Again the President yelled, "Moses!" and again the man stared ahead and didn't answer. The Secret Service agent went up to the man in the white robe and whispered, "You look just like Moses. Are you Moses?" The man leaned over and whispered back, "Yes, I am Moses. However, the last time I talked to a bush, I spent 40 years wandering in the desert, and ended up leading my people to the only spot in the entire Middle East where there is no oil."
