Query: This book is just funny.

I saw this book and just couldn't resist it. In fact, I got it for my husband (we have a toddler, but this book is too wordy for him right now, he'll enjoy it in the future), who laughed until he cried the first time he read it. Yes, it's gross, but the book is genuinely funny; it doesn't only rely on shock value. The graphics are great, too, very trippy.
