Playground Jungle: New Site / Project!

In the midst of all these new books, I have a new site: Playground Jungle, which is all about the "folk process" in playground rhymes, songs, jokes, and stories. Please note that many of these are "by kids, for kids," as opposed to "by adults, for kids." As such, most of them aren't exactly appropriate for kids. Anyway, I need your help! What songs did YOU sing when the teacher wasn't around? Come by and leave a comment or two - let's see how far back these go and how far they spread!
