New Yorkers kept it classy last weekend and left their pants at home for 12th annual No Pants Subway Ride.  The prank, which is organized by Improv Everywhere, asked subway riders to wear their regular winter clothing only without their pants. The catch is that participants had to act as normal as possible.
