What are some smart jokes?

One day, Zhu Zhishan told Tang Bohu: There lived a widow in the back mountain. She had been a widow for three years. She regarded chastity as her life and only raised an eagle to depend on her. If you can deal with this woman, then I, Zhu Zhishan, will admire you. Tang Bohu thought about it and asked Zhu Zhishan to come back in a few days to hear the news. Two days later, it started raining heavily. In the middle of the night, Tang Bohu climbed up the back mountain and arrived at the door of the widow's house. Tang Bohu knocked on the door and asked, "Can you let me take shelter from the rain?" The widow opened the door. It turned out to be Tang Bohu, a talented man from Jiangnan, and she quickly let him in. Tang Bohu came in, thanked him profusely, and then asked, "Can you take off the wet clothes?" When the widow saw that the clothes were all wet, she quickly put the clothes on the stove to dry. At this time, Tang Bohu asked again: "Sister-in-law, I'm thirsty. Can you lend me a ladle so I can drink some water?" The widow quickly gave Tang Bohu a ladle.

Tang Bohu finished drinking the water, looked at how late it was, and asked the widow: "Sister-in-law, can you let me spend the night here?" The widow thought for a while, and it was raining heavily outside, so she agreed. Led Tang Bohu to the guest room, Tang Bohu entered the guest room, was not polite, and fell asleep. At dawn the next day, Tang Bohu got up early and quietly walked into the yard. Sure enough, he saw the eagle that depended on each other. Tang Bohu caught the eagle and plucked out all its feathers; then he returned home without even saying hello to the widow.

A few days later, Tang Bohu and Zhu Zhishan were playing chess at home and heard someone knocking on the door. Zhu Zhishan opened the door, and it turned out to be the widow. As soon as the widow saw Tang Bohu, she yelled in Mandarin: "Tang Bohu, Tang Bohu! You are a scholar from the south of the Yangtze River, a talented man, why did you do such a dirty thing? I thought you were pitiful that day, so you opened the door with kindness. Let you come in. If you want to take shelter from the rain, I will let you take it off. If you want to take it off, I will give it to you. If you want to spend the night, I will let you stay the night. Why did you pluck all my eagle feathers?"

Zhu Zhishan was dumbfounded as he listened...
