Wayside School Gets a Little Stranger (Used Paperback) - Louis Sachar

Before you enter Wayside School, you should know that it’s a thirty-story building with one classroom on each floor. Mrs. Jewls teaches the class on the thirtieth story. Miss Zarves teaches the class on the nineteenth story—except there is no nineteenth story, so there is no Miss Zarves.

Understand? Good. Explain it to Calvin.
