Is it illegal for teachers to play games and joke in class?

Teachers often tell jokes in class, and they are all beaten. Young people laugh at them, unlike the teacher who said, Oh, some students don't need it, which makes me embarrassed. I don't want anything to do with the teacher. In my opinion, everyone has the right to laugh or not to laugh, but if the teacher says that some students don't want to be serious, I want to express my opinion, and I don't specifically specify that you can't, so I think. You don't want to stay with him for a week. Maybe the teacher said that some short students don't laugh, but A Gates doesn't mean you.
