Count till fifty

The teacher walked into the classroom to find words like "cunt" and "cock" scrawled all over the blackboard. "Children," she said, addressing the classroom, "you are much too young to use vile language like that. Now we're all going to close our eyes and count up to fifty. Then, while our eyes are closed, I want the little boy or girl who wrote those words on the board to tiptoe up and erase them." At the signal, the teacher and the children all closed their eyes. Then the teacher counted out loud, very slowly. When she reached fifty, she said, "All right. Everybody open their eyes." All eyes went to the blackboard. None of the words were erased. But below them was the message: "Fuck you, teacher! The Phantom strikes again!"
