Are there any jokes suitable for the active atmosphere in class?

One day, the wild goose was seen by the teacher in class. The teacher looked at him mercilessly and prayed to God with the geese: Alas, I am dead. This is a voice saying: you are not dead, son! Hit the teacher with an eraser quickly. Dayan picked up the eraser and threw it at the teacher. The teacher turned red with anger. This is a voice saying, son, you are dead this time.
