This is a real incident that happened in the life of one of the greatest scientists of the millennium - Albert Einstein. That was the time when Einstein had discovered the theory of relativity (i.e) the apparently simple equation 'E = mc^2'. So Einstein wanted to explain it to as many people as possible and he set out a trip to near by places, and everywhere he was on stage explaining his theory of relativity.

He usually went with his driver who was over fed with the knowledge of theory of relativity, as he would have heard that wantedly or unwantedly all the times Einstein was giving the presentation. Seeing the respect and welcome that Einstein got in the places where-ever he went to explain his theory of relativity, the driver wanted to taste that feeling for some time.

So before they went for the next place to give his presentation, his driver told Einstein that he would be Einstein for that place and asked Einstein to take the role of the driver for this place alone. It was not so difficult for his driver to impersonate Einstein as it was the time when people knew only the name 'Einstein' but have not seen him. Einstein was a bit hesitant to do that as there would be questions he would have to answer, but his driver was so interested in doing this and so he told Einstein that he would take care of anything that comes out of this.

Einstein thought for a while and he also agreed to try it out, having a gut feeling in his mind that his driver is going to be in a difficult situation when questions arise during the presentation. The place came and the driver got out as Einstein from the back seat and Einstein was driving the car. The driver got a great welcome and he went on to the stage to start explaining theory of relativity. He went on with such a flow that even Einstein was surprised about his way of explaining. It was as exact as it would be if Einstein himself had explained it.

The situation that Einstein was expecting for, came very soon when one of them in the crowd raised his hand for a question. Einstein was eagerly waiting for some question to come out but the driver who was acting as Einstein told that person all the questions will be answered at the end. So Einstein had to wait till the end of the presentation and that person in the crowd again raised his hand for a question.

The driver asked him to proceed with his question. He too asked a question. The driver was thinking for a while and the entire hall was so silent. Though Einstein was enjoying the situation, he also had a fear that his name will be spoiled if his driver did not answer the question. He did not know what to do. After a few seconds of thought, the driver, with out hesitation, told this,

"I thought you are going to ask some thing that is really worth ME answering. For this question EVEN MY DRIVER CAN EXPLAIN THE ANSWER!!" Saying this he called Einstein to the stage and made him answer the question after which the driver got a big round of applause. Einstein was very happy to have such a thoughtful driver who could manage the situation neatly.
