This collection of knock knock jokes is as corny as only knock knock jokes could be. And these jokes are for kids as most knock jokes are. So this book accomplishes what it sets out to do. The book is divided into chapters of topics. Some make sense, some don't. Remember, this is a knock knock joke book. One chapter that makes sense is "I Didn't Come Here to be Insulted." These jokes are for pugalists. Knock knock. Who's there? Dummy. Dummy who? Dummy a favor and get lost. This is a fun books for kids. ( )

Humour for the young and punny. Knock knock jokes just make me groan. I thought our family would be done with this book in weeks but a decade later it still gets used often. I do not recommend allowing this book in the car for long trips. ( )
