We’ve all met him by now… Pizza Rat. But where did this rodent, who appears to have superhero-like powers, come from?

Well, where there’s a superhero, there’s his or her origin story, and Conan O’Brien reveals Pizza Rat’s. Little did we know that Pizza Rat actually made the pie himself, taking only one slice before rushing off to catch his train.

Perhaps if Pizza Rat was bitten by a radioactive Italian, or was sent here by a planet of pizza-making rats, it would have made for a better movie. Either way, please watch this.
