Book excerpt: Tall butts, short butts, round butts, flat butts. Butts on mummies and butts on mommies. Butts on giraffes and elephants and dogs and... FISH? Yes, even fish butts are celebrated in this tribute to backsides, rumps, tushies, keisters, heinies, and derrieres. Dozens of funny rhymes and pages of laugh-out-loud pictures pay homage to a body part that keeps kids and grown-ups giggling with glee. Bottoms up!
