Knock Knock, written by Tammi Sauer, reviewed by Judy Hauser

Summary: This is a cute book for the preschool through kindergarten set. A bear gets a lot of knock knock jokes from his friends as he prepares to hibernate. Young children will enjoy the corny knock knock jokes and the big, bold illustrations by Guy Francis. As the bear prepares to sleep for the winter different friends knock on the door with jokes such as "knock knock who's there." The answer is "Ken." "Ken who?" the bear asks. "Ken you let us in already?" The audience for this book will probably find it funny and enjoyable and give them a new repertoire of jokes to use on their friends and family. 

Straight Talk for Librarians: This book will provide some fun and laughs for young children. And if they are not aware of knock knock jokes this will teach them well.
