Dr. Seuss's Sleep Book, commonly referred to as The Sleep Book, is a children's book written by Dr. Seuss in 1962. The story centers on the activity of sleep as readers follow the journey of many different characters preparing to slip into a deep slumber. This book documents the different sleeping activities that some of the creatures join in on: Jo and Mo Redd-Zoff participate in competitive sleep talking and a group "near Finnigan Fen" enjoys group sleepwalking. It opens with a small bug, named Van Vleck, yawning. This single yawn sets off a chain reaction, effectively putting "ninety-nine zillion nine trillion and two" creatures to sleep. Summary The book is written in the style of a reporter on the news who is reporting on the number of sleepers in the world. The book starts with a "very small bug" named Van Vleck yawning. The narrator then tells the reader that this is very important news and goes on to explain that a yawn is contagious and will cause sleep across the countryside. The narrator then takes us around the world to various locations where people are going to sleep, such as Herk-Heimer Falls, the Castle of Krupp, and the towns of Culppeper Springs and Mercedd. Various silly groups of people go to sleep together, such as a "Hinkle Horn Honking Club". Various creatures go to sleep too, such as a Collapsible Frink and the Chippendale Mupp. The narrator explains that they count the number of people and creatures asleep using an "Audio Telly O-Tally O-Count" which spies on people to know when they went to bed. The narrator then explores the latest news in the sports of sleeptalking and sleepwalking before returning to the previous standard of discussing various locations (such as the Zwieback Motel and the District of Dofft) and creatures (such as the Foona Lagoona Baboona and a Jedd. Then the book explains that "Ninety Nine Zillion, Nine Trillion and Two" creatures are asleep and then asks "What about you?" The final line of the book is a "Good night", which is unmetered.
