Thanks!
Let's see some classroom jokes.

WHO IS STUPID
A teacher was trying to make use of her psychology courses. She started
her class by saying, "Everyone who thinks you're stupid, stand up!"
Then little Johnny stood up.
The teacher said, "Do you think you are stupid, Johnny?"
"No ma'am, but I hate to see you standing there all by yourself!"

AN ESSENTIAL CORRECTION
Teacher: Walter, why don't you wash your face? I can see what you had
for breakfast this morning.
Walter: what was it?
Teacher: eggs
Walter: Wrong. That was yesterday.

BIG HANDS
Teacher: If I had seven oranges in one hand and eight oranges in
the other, what would I have?
Student: Big hands
