What is the funniest joke?

While a student on duty was cleaning the classroom, the teacher came in to check the hygiene. He casually touched the globe and found it covered with dust. He asked the students on duty. When the students looked at it, they suddenly realized that the place you touched was the Loess Plateau.

Once upon a time, there was a fool whose father-in-law was coming. His father was afraid that he would say something wrong, so he told him: When my father-in-law asks about the livestock at home, you just call it a little beast, which is not worth mentioning. If you ask about the family's financial situation, you say that the little husband is incompetent and the father is in charge. If he mentions the paintings at home, you can say that they are all Tang Bohu's paintings. With that, my father left. After a while, my father-in-law came and asked the fool, where is your father? Silly said: little beast, stop talking. My father-in-law was taken aback and thought he had heard wrong. He asked his daughter, how could she be stupid enough to say that the little husband was incompetent and the father was in charge. My father-in-law was very angry after hearing this and scolded you for what you said. Silly to say that this is all Tang Bohu's words.

Are you kidding? Pick me.
