The 3rd grade teacher had to leave her classroom for a few minutes. On returning, she found the children in perfect order. Everybody was sitting absolutely quiet.
She was shocked and absolutely stunned. She said "I've never seen anything like it before. This is wonderful. But, please tell me, what came over all of you? Why are you so well behaved and quiet?"
Finally, after much urging, little Julie spoke up and said, "Well, one time you said that if you ever came back and found us quiet, you would drop dead."
