The subway is famous for many things, many of them unpleasant. The New York City subway, for example, is notorious for its disgusting rat population.
If you’ve ever ridden the NYC subway, you know you can’t stand on a subway platform without seeing at least one rat run by. Some of those suckers are as big as a purse or a carry-on bag. Maybe you remember Pizza Rat, the infamous rodent seen dragging a huge slice of pizza down the NYC subway stairs.
