When Einstein Became Driver

while the real Einstein, dressed as the car driver, attends it.
But in the crowd, there is one scientist who wants to impress everyone and thinks of a very difficult question to ask Einstein, hoping he won’t be able to respond. So this guy stands up and interrupts the conference by posing his very difficult question. The whole room goes silent, holding their breath, waiting for the response.
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 reply to it for me.”
