This picture of a giant rat is going viral, and the only thing more baffling than the picture itself is trying to find out where it came from. It first went viral in July, with someone claiming that his sister's friend caught it in the U.K. This was allegedly debunked, though, with reports that it was found in Germany. It then went viral again a few days ago, with someone claiming again that it was "just caught" in London. And again, people were like "nah, it was in Germany." On top of that, a reverse Google image search finds that instances of the image cropped up as early as January, but those could easily be forged.
