Originally published in 2001 by Pan MacMillan in Australia as The Day My Bum When Psycho, this book is well-known and loved and has become a humour classic. It was recommended to me by a high school student who described it as his favourite book; I am so glad he did. Otherwise I would have completely missed out on the delights of Andy Griffiths’ writing.
In case you hadn’t guessed by the title, this book is built around toilet humour. Adults might groan, but kids will laugh out loud. The story centers on twelve year old Zack Freeman and his butt, which has been secretly detaching itself from Zack at night and running around recruiting other butts for the butt revolution. When Zack follows his butt one night, he discovers the enormity of the butt revolution and meets a crack squad of butt-hunters, Silas Sterne and his daughter Eleanor, plus Kicker, Smacker and Kisser, skilled in various schools of butt-combat. The story follows Zack through a series of smelly events in the Brown Forest, the Great Windy Desert, and eventually to the enormous buttcano and a battle against the massive butt army of The Great White Butt.
Scholastic lists the reading level as 3.9 and recommends this book for grades 2 to 5, but I think readers of all ages who thoroughly enjoy a gross-out story will enjoy it. 150 pages of butt puns and fart jokes were a little too much for me, but I did enjoy the book. I have not yet read the sequels, Zombie Butts from Uranus and Butt Wars: the Final Conflict (originally Bumageddon: the Final Pongflict in Australia).
