At 3 p.m. Sunday, participating New Yorkers stripped down to their festive underwear to kick off the 10th annual "No Pants Subway Ride," tucked their pants away into their bags and rode on as usual as unsuspecting passengers gawked away.
The party, organized by the New York-based group Improv Everywhere, only took place from the waist down -- pantsless transit riders kept their top halves fully clothed, donning scarves and gloves as the temperature hovered around a far-from-balmy 30 degrees. According to organizers, at least 3,500 people participated in New York, eventually converging in the city's Union Square to celebrate.

The group's founder, Charlie Todd, said a pantless subway ride is a good way to break up the monotony of the cold winter months. "New York winters can be really brutal, and when people start to go a little crazy, it's nice to have an outlet," Todd told The Wall Street Journal.
New York wasn't the only city to get in on the action, though. Riders went bottomless in 50 cities in 24 countries Sunday, from Mexico City to Boston. On a Facebook page, organizers of the Washington, D.C., branch of the event made it clear that it wasn't advocating full nudity. "Note this is NOT a nudism event or group, nor is it affiliated with any nudism event or group. Undergarments should be selected which conceal all 'naughty bits,'" they wrote.
