While it has become commonplace to find furry things with tails riding the subway, they tend to be rats. But late Friday night, passengers were greeted by a much rarer sighting: an opossum. It was spotted underneath the seat of a Manhattan-bound D train in Brooklyn. Cops attempted to evict the fare-beater at the West Fourth Street station, however, after it started acting pissed off, they retreated. Although the New York Times reports that police called in animal control agents to meet them at a Bronx subway yard, it’s not clear who removed the marsupial.
