Once Moses was walking down the street and up came along Bush.
Bush started to say hi when Moses turned and scurried away. The
next day, Moses was walking along the street and met Bush again. As
before, he turned around and ran away.
Frustrated, on the third day, Moses was out walking again, when he
met Bush, and promptly turned and ran. Bush went to chase after
him. After catching up with him, he asked why Moses ran whenever he
saw Bush.
Moses replied 'The last time I'd talked to a bush, I spent 40 years
in the desert.'
