Nanny Ogg was right!

There are lines I try not to cross on this blog. However, I'll cross some of those lines for an obscure Terry Pratchett joke. If you don't know the Discworld novels -- especially the unique folk songs of Nanny Ogg -- you will probably regret clicking this link. If you are up on your Discworld lore, you'll get the joke... but you'll still probably regret clicking the link. So, having thrown up a barricade of caveats, proceed at your own risk.
