Here it is the nirvana book for all those young male reluctant readers who live only to see and say the word butt and anything else related to the butt. He has run amok in bathroom humor. For these readers this book is absolutely hilarious. I have actually had some pretty tough fellows for whom book is the ultimate four-letter word, look up to me with awe and perhaps a grudging respect, as they say, 'I didn't know they made books like this,' as I pull it off the shelf for them. Happily Griffiths kept at it and wrote more so there's a series. Then, he wrote the 'Just' series which is equally entertaining. Beware, lest your butt lead you into battle. Prepare for gas warfare, men.
