Did you leave some poo on the subway this morning?

A tipster sent in this poo-rtrait of some (possibly your) poo, snapped on the R train during rush hour. The origins are unclear:

Can't tell if it's human or dog poo; but poo is poo.

If you or your dog did lose some poo, you have 30 minutes to collect it before it becomes official property of the R train.

Tick tock.
