This one is partially based in real life on two counts.

One - yes, on one occasion, I was stuck in a friend's house with no toilet paper, and he kept the spare toilet paper in the hall closet as opposed to the cabinet under the bathroom sink within arm's reach of the toilet. I still don't understand that one.

And two - when I'm at home, I never use toilet paper anyway. It's a terrible way to clean yourself. If I'm in my own personal bathroom, I just conclude my bowel movement with a quick hose-off in the shower. I can't afford to install a bidet.

Seriously, who came up with the idea of wiping poop off of yourself with paper? If you were out at a public park, and accidentally slipped and mashed your hand in a warm dog turd, would you wipe it off with a dry napkin and call it clean?
