[The story is of a man going up for his first parachute jump. He asks the instructor what to do
"Jump out, wait until you're clear of the plane, then pull the ripcord"
"What if the parachute doesn't open?"
"Pull the cord for the reserve chute"
"What if that doesn't open?"
"Shout "Geronimo" and head for the ground"
So the man makes the jump. A bit later he is seen flapping his arms and tapping on the window of the plane
"What was the name of that Indian again?"]
