"John" is the seventeenth chapter of Sideways Stories From Wayside School. John can't stand on his head, which he needs to do in order to read the blackboard. He sees everything as upside-down. When he attempts to stand on his head, he falls over, evidently flipping his brain over, thus allowing him to see things right-side up.
- John was one of the smartest boys in Mrs. Jewls's class. But he had one problem. He could only read words written upside down. Nobody ever wrote anything upside down.
- "Of course you can, John," said Mrs. Jewls. "If Joe can stand on your head, so can you."
