An Indian chief is driving his Cadillac somewhere in Nevada.
Suddenly his car gets broken.
He examines it, and reveals that a technician must be called.
But the chief has only $4, and no credit card. So he gathers some wood, makes a fire and signals his tribe with its smoke: “Hey, send somebody to my location with $500!”
The tribe accepts this signal, but to make sure of its meaning, signals back – once again, with the smoke: “OK, chief, but why so much?”
At this moment a ground test of a nuclear bomb is being held on the test field nearby.
A huge mushroom-like cloud of smoke rises into the sky…
The tribe signals: “Ok, Ok, chief, we just wondered, why be so angry?”
