This book is a great book for children on the iPad. It fills up the whole screen, and is easy to read. It's not too long but long enough to enjoy with the kids before bed or in the car.

My family enjoys reading these jokes. I love the silly artwork and jokes a lot. If your looking for a few good laughs for you and the kids, this one is a must.

Very enjoyable for many ages. Great knock knock jokes! A great buy.

These knock knock jokes will knock your socks off! They are hilarious! This is the first picture knock knock jokes book that I have seen and it is very entertaining for my kids. It is fun to have them guess who is behind each door. That makes this book very interactive and fun for kids. High five and five stars!
