As if riding on the subway weren't sensory overload enough, this poor woman is the subject of a "no pants" prank courtesy of the Improv Everywhere [1] jokers. She doesn't know whether to laugh or to be startled by the fact that slowly, all the dudes getting on the subway car are wearing boxers--so she just clutches her purse. (She can be thankful it wasn't "tighty whiteys" day, God forbid!)
