Three prisoners

Three
prisoners, an American, a Frenchman, and a Pole, are scheduled to be
executed by firing squad. They bring out the American and stand him in
front of the pole. He points and shouts, "Tornado!" they all look and
the American runs away.

Next, they place the Frenchman in front of the firing squad. He yells "Earthquake!" They all hit the dust and the Frenchman escapes.

Next up is the Pole. He looks around and shouts "Fire!"
