There are two people flying in a private plane. One is a very important scientist. He was considered the most intelligent person on Earth. The other was his servant.
As they were flying , the Captain announces that the plane is going to crash because of engine failure. The captain enters the cabin. "There are only two parachutes. One of us will have to stay in the plane" he says as he points towards them. The scientist quickly gets up and grabs the parachute. He says "I am very important. The world needs me" as he jumps off the plane. The pilot stares at the servant. "Now which one of us will stay on the plane?", he asks. "Don't worry," the servant replies "He took my backpack!"
