A plane carrying the Priest, a Hippie, and the smartest man in the world is flying along, when all of a sudden the pilot bursts from the cockpit. He shouts that the plane is going down and there are only three parachutes, and he leaps out the door wearing one of the parachutes.
Almost immediately after the smartest man in the world stands up and says, "I'm the smartest man in the world, it would be a tragedy if I were lost!" He takes a Parachute and jumps out.
The Priest looks at the Hippie and starts to tell him that God would want him to give his life for another, when the Hippie interrupts and says, "Hey man Don't worry."
"The smartest man in the world just jumped out of the plane with my backpack!"
