It's fun to pee on things and fathers point this out to their potty-training boys showing them all kinds of different places they will pee in the world. They point out that it's better to pee elsewhere than in your pants. This book offers a sense of accomplishment and bonding between father and son. Mothers may find it inappropriate but, such is the nature of these things. That book, titled Use the Bathroom and Wash Your Hands is much shorter than this book and is much less fun and also, at times, much less practical. Go get em boys! This book is for you!
