Sideways Stories from Wayside School

This book is FANTASTIC. It is made up of 30 chapters, each about a teacher or kid in the classroom on the 30th floor of Wayside School, a school that was built, by accident, on its side (thirty classrooms, straight up). The chapter on Joe, the kid who cannot count but who somehow always gets the right answer is alone worth the read. The classroom is filled with dead rats who show up in kids' clothing, evil teachers who turn kids into apples, kids who trade names and kids who want to sell their toes. It is bizarre and creepy and hilarious and makes no sense. Perfect humor for early elementary kids.
