The debate over whether you hang your toilet paper "over" or "under" is one of those chicken-and-egg things that people will argue about until the end of time.

In the "over" position, the paper hangs to the front. In the "under" position, the paper hangs to the back. People have been arguing FOREVER over which way is "right." But not anymore.

A writer just dug up the original patent for the toilet paper roll from 1891. It's by an inventor named Seth Wheeler, and it actually answers the question, once and for all.

In the patent drawing, the roll is in the "over" position. So that's your definitive answer.
