What kind of joke is a cold joke?

1. I remember a buddy in our dormitory grabbed someone else's buns and said while eating: this stuff is only suitable for stuffing your ass. 3. I remember when I was a child, the primary school teacher scolded a student: "I will kick you out with a slap!" We want to laugh but dare not. 4. Several of our middle school classmates once rode out. One classmate kicked another fatter classmate's foot and wanted to scold him, saying, I put out a pig's hoof and flew a foot ... 5. A girl in our dormitory fiddled with another mm's bangs: Look at this mess, like a dog's paw scratching? 6. Someone in the dormitory jumped up after drinking someone else's boiling water and shouted, * *, it's so hot that pigs can't stand it ... 7. In college, there were many people in the men's toilet after class, and everyone lined up. At this time, classmate A asked the second one behind him to say "Come here", and B was in tears. I quickly said, why does the back look familiar? 8. One of my junior high school classmates likes to touch other people's heads. One day, he touched someone's head and said, "It's quite round." That classmate got bored and took his hand and said, "Don't give me an egg here." 9. A classmate in my class often writes wrong words, and once wrote an article, one of which read: I saw a pile of cow dung on the road today, ah, a catty was a fright. Later, the teacher commented: It doesn't matter if no one stops you from eating it all. 10. One day, one of my classmates was walking on the road. Suddenly, a mouse jumped out and scared him. He opened his mouth and cursed "* *, you scared your dad!"
