Recently while going through an airport during one of his many trips, President Bush encountered a man with silver 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 ahead. Again the President said, "Moses!" in a loud voice. The man just kept staring ahead, never answering the president. Soon a secret service agent came along and President Bush grabbed him and said, "Doesn't this man look like Moses to you?" The secret service agent agreed with the President. "Well," said the President, "Every time I say his name, he just keeps staring ahead and refuses to speak. Watch!" Again, the President yelled, "Moses!" and again the man stared ahead. The secret service man 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, "Yes, I am Moses. But the last time I talked to a bush, I spent 40 years wandering in the desert!"
