I think the book is fun, and I love how the principal moonlights as a super hero. And the flip-o-rama pages are always a hit with my kids. My boys love being in charge of the action pages. George and Harold are typical fourth graders. I love their creativity and their comics.
This book is great for middle and upper elementary grades. Not only is the book hilarious and full of their type of (potty) humor, the book helps get kids excited to read, and who can argue with that? Funny read for young children!
