Read a joke about cats and dogs:

A rich man married his daughter and told all the young people that I have a noble pet cat. If anyone can make it shake its head first, then nod, and finally jump into the swimming pool automatically; I will marry the girl to him and give him half of his fortune as a dowry; As a result, many people tried and failed; Finally, a young man said, I'll try! He walked up to the cat and asked, Do you know me? The cat shook its head; Ask again: Are you awesome? The cat nodded; The young man flew up and put the cat T into the swimming pool! The rich man shouted, You're a foul! ! ! I'm talking about making it jump into the swimming pool automatically; I'll give you another chance, but this time you have to let it nod first and then shake its head; Finally, he jumped into the swimming pool automatically. The young man came to the wet cat again and asked, Do you know me? The cat nodded and asked, Are you still a cow? The cat shook his head and the young man finally said, then you know what you should do, right? The cat thought for a moment and swished into the swimming pool. . . . .
