Funny things in our class

Music class, the teacher asked: Who still remembers the notes we learned last time?
Solo: One... two... three...
All together: Guess!!
Teacher laughed: I'm not guessing

That day, P.E. class couldn't be held because of the rain, and in the classroom, the geography teacher came to take over the class
All together: Protest, protest, protest...
Later, the geography teacher was driven away by our outrage

Computer class, a new teacher came, a man, who started teaching immediately. I said to my deskmate: What's this teacher's surname?
Deskmate, after hearing this, loudly said: Screw; someone just asked your first name!
The teacher's class was forcibly interrupted by our math teacher A Su's class. Our class quietly copied the problems from the blackboard when a series of sounds of desks and chairs being overturned came from Class 1. A Su went (he is the head teacher of Class 1), then a male student from Class 1 came out and stood at the door of our class. A Su thoughtfully gave him a chair to sit... returning to our class, he said: I brought an assistant to help with the class. The whole class laughed, and A Su said: Really, I'm not afraid of you laughing
