Query: Tongue-twisting, dark and hilarious.

I absolutely love this book. I received it as a gift for my son from a friend years ago, and it's never lost it's charm. The rhymes take some skill, and the rhythm is entertaining for even adults. The story is hilarious, creative, unique and just... it's just amazing.Buy the book if you have boys, especially those who like pranks or monsters. You won't regret it.
