One day a few years ago a very funny thing happened to a neighbour of mine ,He is a teacher at one of London's big medical schools ,He had finished his teaching for the summer team and was at the airport on his way to Russia to give a lecture.
He had put a few clothes and his lecture notes in his shoulder bag ,but he had put Rupert ,the skeleton（人体骨架）to be used in his lecture ,in a large ,brown suitcase（箱子）,At the airport desk ,he suddenly thought that he had forgotten to buy a newspaper ,He left his suitcase near the desk and went over to the shop .
When he got back he discovered that someone had taken his suitcase by mistake ,He often wonders what they said when they got home and found Rupert .
