The great scientist Albert Einstein was on a lecture tour of America, and was starting to feel the pace.
“I am sick and tired of all these meetings”, he moaned to his driver, who had a shock of white hair and looked remarkably like the great man.
“All I do is say the same old things over and over again”, Einstein added, sounding like he had really had enough of this lecturing tour already.
“Yes, it must be tiring”, said his driver. “I have sat through all your lectures waiting for you, and even though I know nothing about physics and stuff, I think I could give the lecture myself. I have sat through so many of them, I can even do your accent”.
“Eureka”, said Einstein. “I have a great idea. Why don’t you do the next lecture for me, and I’ll have a rest among the audience pretending that I’m your driver”.
So, the two of them swap clothes shortly before arriving at the venue, and Einstein drives up to the door.
The driver does the lecture as planned, and everything is going well until a scientist in the audience, trying to look clever, asks a particularly complex question with endless jawbreakingly long words.
The driver is thrown for a moment, but then looks at the scientist with a disdainful expression and says: “That is such a simplistic question that I’m going to let my driver answer if for me”.
