An Indian chief is driving his Cadillac somewhere in Nevada when his car breaks down. He examines it and finds 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 somejoke to my location with $500!” The tribe accepts this signal, but to make sure of its meaning, signals back – once again, with smoke:
“OK, chief, but why so much?”
At this moment a ground test of nuclear bomb is 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, no need to get mad!”
