"Over the course of a long walk across a city, one curious kid needs to know: 'Does it have a butt?' Everything from sheep to ghosts to dinosaurs is subjected to this all-important question, and Dad is a never-ending source of answers. On a laugh-out-loud father-child ramble, we come to see that every butt, from a bullfrog's to a zombie's, has its own distinctive, and distinctively hilarious, quality."-- Provided by publisher
