One of the world’s best scientists is preparing to speak at an important conference. On the way there he tells his driver, who looks a bit like him:”I’m sick of all these conferences. I always say the same things over and over!”
The driver agrees: “You’re right. As your driver, I attend all of them and, even though I don’t know anything about science, I could give the conference in your place.”
“That’s a great idea!” says the scientist. “Let’s switch places then!”
So they switch clothes and as soon as they arrive, the driver dresses as the scientist, goes on stage and starts giving the usual speech, while the real scientist, dressed as the car driver, sits in the audience.
However, in the crowd there is one man who wants to impress everyone and thinks of a very difficult question to ask the scientist, hoping he won’t be able to respond. So the man stands up and interrupts the conference. The whole room goes silent and holds their breath, waiting for the scientist to answer.
The driver looks at him, dead in the eye, and says: “Sir, your question is so easy to answer that I’m going to let my driver answer it for me.”
