Moses was walking down the street when he bumped into the ex-President. "Hello," Bush said. "Nice weather we're having, huh?"

Moses took one look at the President, turned and ran in the other direction. The next day Moses was walking down the same street and there was Bush. Again he tried to initiate a conversation. Again Moses turned and ran away.

Bush was tired of this bizarre treatment, so the next time Moses ran away from him, Bush followed. When he caught up, he asked Moses what was wrong.

Moses said, "The last time I talked to a bush I spent 40 years in the desert."
