At lunch he met a young man, one of his friends. The young man said that he has an uncle with him. He told Mark Twain that his uncle never laughed or smiled, and that nobody and nothing were able to make his uncle smile or laugh. “You bring your uncle to my talk tonight,” said Mark Twain. “I’m sure I can make him laugh.”
That evening the young man and his uncle sat in the front. Mark Twain began to speak. He told some funny stories. This made everyone in the room laugh. But the man never even smiled.
