Jack Prelutsky! He's one of my favorite children's poets, and kids LOVE his stuff! He's silly and quirky. Here's an excerpt from "Be Glad Your Nose Is On Your Face:"
Be glad your nose is on your face,
not pasted on some other place,
for if it were where it is not,
you might dislike your nose a lot.
Imagine if your precious nose
were sandwiched in between your toes,
that clearly would not be a treat,
for you'd be forced to smell your feet.
