Calvin asks Susie who's sitting at Miss Wormwood's desk. Susie tells him that Miss Wormwood is sick, and they have a substitute teacher. Calvin yells that he wants to see her teaching certificate.

The substitute teacher introduces herself to the class. She mentions that Miss Wormwood left instructions about what they had to go over so there wouldn't be problems. She notices a note that Miss Wormwood left. She asks which student is Calvin. He yells out "Not me".

Calvin tells Hobbes he had a substitute teacher at school. Hobbes asks if he liked her, and Calvin says he guesses so. Hobbes wonders why he "guesses". Calvin says it's hard to tell, since she went home at noon.
