It's in New York in an underground tunnel (a train tunnel, but that could connect with sewer tunnels where his home is), it's pizza, this rat is on the move like ninja status.
It's a brown rattus 'norvegicus', the most aggressive of the rat family (or at least one of them). He apparently didn't give a **** as he crawled up a guy's leg and pretty much into his face on a train. Ballsy. This is awesome. I've had 'em as pets and this is not at all uncommon behavior for them to drag food objects as large if not larger than themselves around.
Kinda like that video of that one rat that had caught a pigeon live and was fighting to drag it down the hole to its nest for dinner.
