Indoor pluming is one of the crowning achievements of mankind. Too bad this video has ruined it for everyone.

The sadistic bastards at National Geographic decided to show the world just how easily a rat can make its way from the sewer line to your toilet bowl. As a result, you’ll never be able to let your exposed genitals hang down from a toilet seat again.

A rat’s ribs are hinged at the spine, enabling it to easily squeeze through the tightest spaces—like the pipes draining your toilet. And rats are great swimmers too; they can hold their breath for up to three minutes.

From now on, I’ll be defecating outside. Yes, squirrels love nuts, but at least I’ll be able to see them coming.
