A Book of Foolishness for Kids: Things to think about when you don't have anything better to do

Do you know how far there is, at all? Or where you'd get if you dug straight down clear through the Earth? Or how hot is hot? Or if your dog thinks? Funny lot of questions in a book for kids. But even grown-ups don't know the answers to some of them. All in a book of poems that don't rhyme. Oh yeah, not to forget foolishness.
