There is a new girl in school.
The class was told to paint a picture of themselves. The next day, one by one, they were showing off their paintings.
The new girl shows an obviously adult-drawn painting, and says that it shows her in her favorite green boots. Shelley Long, the teacher, asks her if she remembered that she was supposed to do the painting, without help from anyone else; the girl said she did it all herself.
The situation escalates, ending with the girl being sent out into the hall until she wishes to admit her painting was not self-made. She talks to the janitor, and gets good advice about her problem.
