( For the benefit of non Americans - US nuclear tests were often held in the Nevada desert)

An Indian chief is driving across the Nevada desert when his car quits. (This is before cell phones) He knows he will need money for a tow truck and for repairs.

The chief decides to resort to an old Indian means of communication - so he sends up a smoke signal to his tribe: " Send me $500!"

The tribe signals back: " Why so much money?"

The chief (who has been sitting in the desert for hours) is about to send back an angry reply when a nuclear test blast goes off. The mushroom cloud blossoms up to over 50,000 feet and begins to spread.

The tribe signals: " OK, OK, we're sending the money! Why do you have to get so huffy about it?"

That's funny

The tribe won't mess with him again!
