I checked this book out from the library, knowing that my grandson would love it! He loved it so much, that I went ahead & ordered it for him & it arrived really fast. Parents / Grandparents, be on the lookout if you have precocious children or grandchildren. My grandson got a hold of a permanent green sharpie when spending the night with us & the next morning when I was changing him into clothes, I found that he had scribbled all over one cheek of his hiney! Later, when we asked him if he wanted an arty farty butt, like the boy in the book, he sheepishly, but with an impish grin, shook his head yes!! It was too funny! FYI, green sharpie comes off of hineys with a little rubbing alcohol & a cotton ball.
