Teacher's great humour................

TEACHER: Cindy, why are you doing your maths sums on the floor?
CINDY: You told me to do it without using tables!

TEACHER: Willy, name one important thing we have today that we didn't
have ten years ago.
WILLY: Me!

TEACHER: Ellen, give me a sentence starting with "I".
ELLEN: I is...
TEACHER: No, Ellen. Always say, "I am."
ELLEN: All right... "I am the ninth letter of the alphabet."

Teacher: "George Washington not only chopped down his father's Cherry
tree, but also admitted doing it. Now, do you know why his father
didn't punish him?"
Johnny : "Because George still had the axe in his hand."
