Never doubt a New York City rat's strength and resolve.

The city's rodents are already known to persist in their quest for local food favorites (see: pizza rat, roll rat).

But one astonishing rat in Brooklyn was captured on video dragging by its teeth an entire filled trash bag just to get to a personal pizza crust inside.

Leigh Conner filmed the rat on her block in Crown Heights, near Kingston Avenue and Dean Street, DNAInfo reports.

She told the news website she was getting on her bike when she spotted the trash bag moving away from the curb. That's when she saw the rat crawling out of the trash bag and start to drag it.

It was apparently trying to get at a round pizza pie crust inside.

The rat could be seen tugging and gnawing through the plastic trash bag, then finally getting the pizza crust out of the bag. It scurries away with the dough -- but inexplicably abandons it a short distance away.

Could be this city rat is also pretty fickle.
