This book is about 2 groups, the Yooks and the Zooks, who live separated only by a wall, and are very similar except for the way they butter their bread. This leads to a battle involving constantly bigger weapons, until they come up with the 'big-boy boomeroo', capable of destroying each other's lands. Of course, the book ends before the story does, leaving you guessing on exactly what would happen.
I went through a few stages with this book, making it even better to think about. The first time I heard it, I was about 5, and upset that there was no 'ending'. After a few more times, I decided to use my imagination to create my own ending, which is what many children will do if encouraged by a parent reading with them. As I got older, I realized there was no ending because if it was real, you really wouldn't know how it ended until it happened. This book also made me think about how small differences in people can cause such big problems if you are not open minded. (That was after a few years - in the beginning I wondered why the Zooks didn't just turn their bread upside down and everyone would be the same).
The Butter Battle Book is a wonderful lesson, written in a way that even a child could understand the concept of war, see how differences in people can cause foolish problems, and use their imaginations. I would recommend it to anyone.
