Well, here's something you don't expect to see in the listing for a house on a real estate website: a toilet equipped with a pedal-powered contraption that drags toilet paper across your filthy bits, allowing you to wipe hands free. And, one assumes, leaving a train of vile used TP behind your toilet.
I've got to assume that this thing was made for someone without use of their hands, such as a double amputee, as it certainly doesn't make the wiping process any more convenient. Furthermore, no germaphobe would accept the tradeoff of keeping clean hands for having a roll of feces-smattered toilet paper just sitting there behind their toilet. Why else would this thing exist? And really, the more I look at it the more I get confused about how exactly it functions. What about when you're actually going? Doesn't it get in the way?
