Teacher: "Have you ever seen a humming bird?"
Student: "No, but I have watched a spelling bee!"
Teacher: "You cannot sleep in my class!"
Student: "Well ma'am, I could if you were a little quieter."
Teacher: "Class, we'll have only half a day of school today morning."
Teacher: "We'll have the other half this afternoon."
Why was school so much easier for cave people?
Because they had no history to study!
