Old people make up humorous jokes.

Elizabeth II's grandfather was George V. When George V was old, he once chatted with a friend. He was an old lawyer as old as him. The old lawyer told a joke to George V, and George V was made to laugh. After a while, George V said, Tell me another one. The old lawyer said, all right. He thought about it and told a new one. When the people next to him heard it, they knew that the old lawyer had just told that joke, but George V laughed as he heard it for the first time. George V said with a smile, this joke is more interesting than the one just now. After a while, George V said to the old lawyer, I heard a particularly interesting joke recently. Let me tell you. So he repeated the joke told by the old lawyer just now. Who knows the old lawyer said after listening: Where did you hear such an interesting joke?
