Smartest president ever

A plane with 4 people on board suffers an engine failure. There are only three parachutes. The pilot stands up and says: „I’m Brad Pitt, my kids needs me, my fans needs me, I have to survive.“ he takes one of the parachutes and jumps out of the plane. The first passenger stands up and says: „I’m Donald Trump, I was the smartest president the US ever had and I’ll become the next president. My country needs me.“ He takes the second parachute and jumps out of the plane too. The two remaining passengers are a young boy and an old man. The old man turns to the boy and says: „I’ve lived my life, it was a good one. Take the last parachute and get out of here.“ The boy starts smiling and says: „Don’t worry, we both will survive. The smartest president ever just jumps out with my school bag.“
