A famous scientist was in his way to other lecture when his chauffeur (司机) offered an idea. “Hey, boss, I’ve heard your speech many time. I bet I could deliver it and give you this night off.” “Sound great,” said the scientist. When they got to lecture hall, the scientist put up the chauffeur’s hat and settled in the back row. And then the chauffeur began to deliver the speech. Afterwards he asked if there were some questions. “Yes,” said a professor. Then he asked a high technical question.
