New York subway riders got to see a lot more of their fellow passengers on Sunday.
The bare-faced cheeks were all part of the annual No Pants Subway Ride, where straphangers shed their trousers and finis-the trip in their undergarments.
The tradition was started 18 years ago by an improv group in New York City and has spread to public transit lines from San Francisco to Jerusalem.
Organizers call it ‘an international celebration of silliness.’

It’s the 18th annual No Pants Subway Ride. There were around 2,000 participants in New York according to the organizers
Participants are supposed to act like they don’t know each other and pretend like they are going about their day as normal. All wear winter coats, hats, scarves, and gloves – ‘the only unusual thing is their lack of pants’.
Despite the frigid temperatures, riders in Chicago, London and Paris, shed layers to join in.
Participants are told to get on trains and act as they normally would and are given an assigned point to take off their pants.
They’re asked to keep a straight face and respond matter-of-factly to anyone who asks them if they’re cold

The rules of the event are fairly straightforward: Underpants must be worn and, although flashy designs are allowed, organizers prefer those involved to look – at least from the waist-up – as though they are going about their daily lives.
This is to increase the impact the participants have on the unaware bystanders.
In the inaugural event only seven people took part, but now thousands in major capital cities around the globe participate in what organizers call a ‘celebration of silliness’.
Uniforms and business suits are encouraged to amplify the lower-half effect as are props – bicycles, prams, shopping bags or a briefcase.
