rats

(Animal lover warning: this video is two minutes of one rat dragging its dead brethren around a subway station)

Not satisfied with the squish of day old pepperoni, this NYC subway rat has opted for the opulent crunch of another rat.

If I didn't tell you it was a rat in this video, you probably would have thought an armed gunman had made it onto the train, right?

That's one way to get your cat to fetch your slippers.

Not in the computer, genius.

It really could be any number of horrifying creatures but "rat" is my best guess.
