Four people are in an airplane: the president, the smartest man in the world, an old man and a young girl. The plane catches on fire and there are only three parachutes.
The president gets one and says, “My country needs me!” and jumps.
The smartest man in the world grabs one and says, “Well, the world needs me, since I'm so smart,” and jumps.
One parachute left and the old man says, “You take it, my life is almost over anyway.”
The little girl says, “No. We both can jump.”
Confused, the man asks, “How?” The little girl says, “The smartest man in the world took my backpack.”
