(3) K-3 Illustrated by Pranas T. Naujokaitis. A slapstick but thorough investigation, told in jaunty rhymes, of all the ways in which humans and animals emit bodily gasses. Adults, too, might learn quite a bit from this instructive and playful emporium of gastrointestinal erudition. For instance, "Here's one of nature's stranger facts: / We cannot burp on our backs!" Two pages of facts and trivia are included.

(3) K-3 Illustrated by Mike Moran. Professor P. Poopdeck discusses types of animal waste ("Rabbit pellets, raccoon tubes, / Owl whitewash, and wombat cubes") and how that waste is used by animals ("Termites...poop to make a mighty mound") or humans ("The Mongol yurt...is often sealed with dung of yak"). Amusing cartoonlike art illustrates the humorous, informative text.

(2) PS Illustrated by Mike Lester. In this good-natured hymn of praise, matter-of-fact rhyming couplets cover butt synonyms, characteristics, and raison d'être, as watercolor and scratchboard illustrations place us in scenes from art galleries to ancient Egypt to a fair. The text includes a few nods to natural history or international terms, but the major point seems to be that butts make the whole world one.
