What do you mean, it's up to you, it's up to you?

Once upon a time, a private school teacher farted loudly in class, which made the students burst into laughter. The teacher was angry and knocked on the table with a pointer and shouted,' Laugh! What are you laughing at? Many students stopped laughing, but only one student was still laughing. Mr. Wang pointed to the boy and said, "Stand up for me. What are you laughing at?" Say! The boy smiled and said, "Sir, I just laughed at your fart." The gentleman is furious:' Bullshit! What is fart? Give me a fart at school tomorrow morning. Let me have a look. You can't catch a heavy slap! When the little boy came home glumly and ate with his head down, the little boy's sister asked you why you were unhappy at school today. The little boy told the whole story, and my husband asked me to catch a fart and show it to him tomorrow. How can I catch this fart? The little boy's sister said it was easy. I'll catch it and bring it to you tomorrow. The next morning, the little boy came to school with a small package. He knocked on Mr. Wang's door before the school started. Mr Wang just got up. The little boy said, "sir, I caught your fart." Mr. Wang was also surprised. What he said was just a joke. How can he be serious? Mr. Wang took the parcel and there was a piece of paper with a poem written on it: Fart is a gust of wind, and it comes out without a trace. Grab it or grab it. Mr. Wang untied the rope and opened the package, saying, absolutely! Absolutely! Teacher Niang mistakenly heard that it was cut, so she interjected: What are you cutting? Still using a knife? How many bites does one person chew, but two people can't finish it? Later, it was wrapped in layers of paste, and the volume became smaller and smaller. Mr. Wang still said: absolutely! Absolutely! Teacher Niang was tired of listening and said, cut what! You can wrap it in your mouth in one bite! The best thing to open is a pile of shit, and the whole room stinks. If your husband is angry with your teacher, you know how to eat! Have you eaten now?
