Not that Leaf!

I wonder who decided on the practice of toilet paper. You know at some point there was that one guy or gal in the river who said to themselves, 'I would love to do this in a closet in my house'. The only problem was there's no running water in the closet, so what's a guy who just ate an entire goat to do? Ah yes, a bucket, and look an old shroud, but I can't smear up all my shrouds, lets use something growing from outside, or a fuzzy animal.
