Did you know that half of all people wipe their butts in a different way than you? Some stay seated and some stand. (I'm guessing most girls sit, actually.) And until now, no one knew that their way wasn't universal.

Three years ago, a guy named Kev Kage posted about this phenomenon on CollegeHumor. The piece got a couple hundred comments, and then not much attention (as far as I can tell), until last night it landed on Reddit and got front-paged.

And now, because bloggers always copy Reddit, soon the world will know that half of their friends wipe the wrong way, a way that seems foreign and baffling. Everyone will be asking intimate relations to demonstrate their stance. I know this because my girlfriend and I, bewildered and a little defensive, just carried out this cultural exchange.

You think you know a person.
