There is an anecdote about Mark Twain. The thing is this: Mark Twain was not only a very famous writer, but also a famous speaker and a good joke teller at that time. He often goes to various towns to give speeches and tell a series of jokes. One day, he was walking in the street of a small town. He is going to give a speech here that evening. He met a young man who told him that he had an old uncle who never laughed. Mark Twain asked the young man to bring his uncle to the lecture in the evening. He said he would make him laugh. That night, the young man and his uncle sat in the first row. Mark Twain said to them. He told some interesting stories, but the old man didn't laugh at all. Then Mark Twain told the most interesting story he knew, but the old man's face was still blank. Mark Twain can only leave the podium when he is exhausted. Later, Mark Twain told a friend about it. "Oh," said the friend, "you needn't have bothered at all. The old man has been deaf for many years.
