Once, the chauffeur requested his master Einstein that he will deliver a speech at a scientists' gathering where Einstein was to speak. Einstein agreed to this odd request.
While chauffeur dressed like Einstein and entered the elite gathering, Einstein waited in the car in the driver's seat.
The chauffeur did a nice job at the scientists' meeting and when he was about to leave the room, a professor asked an extremely esoteric question about anti-matter formation.
Without missing a beat, the chauffeur said, "Sir, the answer to that question is so simple that I will let my chauffeur, who is sitting in the car, answer it for me."
