Finding out about this a few months ago was enlightening. Entire classes of messes I've seen in public restrooms that were previously inexplicable short of deliberate action became comprehensible through a combination of stand-to-wipers plus carelessness.

Okay, then let's get rid of wiping too. It's basically non-existent in parts of Asia, and after spending six months doing it their way, I'm a convert, especially when it's the integrated bidet rather than the hose. You just feel so much cleaner afterwards and the savings on toilet paper is an added bonus.
