Einstein's Theory of Relativity is regarded as one of the most important contributions in the twentieth century. In 1921, Einstein was awarded the Nobel Prize for physics. A number of well-known universities invited him to give speeches at their campus.
Once, on the way to a university, his chauffeur said to him, 'Doctor, I have heard your speeches for numerous times. I believe I will speak as well as you if given the chance to stand at the rostrum.'
Einstein understood the chauffeur's intention, so he joked, 'That's a good idea! Since nobody in this university recognizes me, why not you speak on behalf of me. It us really great I can take a good rest then.'
The chauffeur was overjoyed. He acted as Einstein while Einstein the chauffeur.
As expected, the speech by the chauffeur was a great success and won the audience's thunderous applause. However, during the interaction session after the speech, a student raised a question which had not been heard about by the chauffeur. The chauffeur thus could not answer it. Having no answer in mind, he was embarrassed. Luckily, he soon had a brainwave and said, 'This question is too simple. I'll let my chauffeur answer it.' Einstein answered the question immediately and so the chauffeur was out of the embarrassment.
