In a flying airplane are, besides the pilot, the presidents of America, Russia and France, the Pope and a student who is traveling as a backpacker. The pilot tells them the plane has engine trouble and they will have to jump with the parachutes. He jumps himself as the first one. Now there is one parachute less than there are passengers. The American president grabs a parachute, says: I am the leader of the Western World and jumps. The Russian president says: I am the leader of the Eastern World and jumps with the second parachute. The president of France says: I am the smartest president on earth and jumps. Now there is only the Pope and the student left. The Pope says: Come my son, take this parachute and jump. The student says: You are truly a holy man by giving me the last available parachute. The Pope answers: Don't be silly and jump. The smartest president on earth just jumped down with your backpack.
