Einstein's Chauffeur

When Albert Einstein is making the rounds of the speaker's circuit, he usually finds himself eagerly longing to get back to his laboratory work. One night as he is being driven to yet another boring dinner, Einstein mentions to his chauffer ( a man who somewhat resembles Einstein in looks and manner) that he is tired of speech making.
"I have an idea, boss," his chauffer says. 'I have heard you give this speech so many times, I will bet I could give it for you.'
Einstein laughs loudly and says, 'why not? Lets do it!'
When they arrive at the dinner, Einstein puts on the chauffer's cap and jacket and sits in the back of the room. The chauffer gives a beautiful performance of Einstein's speech and even answers a few questions expertly.

Then a supremely self-important professor asks an extremely complicated question about antimatter formation, stop to talk about something else here and there to let everyone in the audience know that he is nobody's fool.
Without a moment's hesitation, the chauffer fixes the professor with a steely stare and says, "Sir, the answer to that question is so simple that I will let my chauffer, who is sitting in the back, answer it for me."

hahaha ... :)
