Funky Question Du Jour
Why is it that the human male, who has relatively smooth skin on most of his body, has pachyderm skin on his balls? I really want to know. For those of the species who are still (or once again) wearing diapers the endless cracks become a poop hazard. If I don't keep a close eye on my two year old he's going to become known as 'Old Crusty Balls'.
In case you were wondering, the picture above is a small piece of this one below. I'm not that twisted.
