substitute

As I have been preparing for the Washington DC trip and the substitute that will take my other classes all this week, one of my seventh grade students who is probably most looking forward to my absence next week reminded me of this children's book that I used to love when I was little.
Miss Nelson is a sweet and kind teacher with a horrible class. But one day when they arrive to school, the class is surprised to find an evil substitute in her place. The substitute looks and acts like a witch--wart and all. And she whips those kids in shape. The class is so relieved and thankful to have the kind Miss Nelson back in the end that they would never dream of misbehaving again. But on the last page in the illustration, you see in the corner of Miss Nelson's room an ugly black wig just like teh evil sub's. Ahhh, the great plot twist , of course, is that Miss Nelson was the evil sub whipping her class into shape.

I tried to find a copy of the book this week to read to the seventh grade just for fun, but alas, I was too busy preparing for my real sub. I wish that I could dress up and be my own substitute next week--it would be a lot easier and a lot of fun ;).
