Annual No-Pants Subway Ride

The No Pants Subway Ride is back. The annual event where people around the globe ride the train with no pants on took place Sunday.

It was started by a group of improvisers back in 2002 in Manhattan.
And it's grown to cities around the world.

Participants are told to act as if nothing unusual is going on. And ride the subway as they normally would!
Organizers call the event an international celebration of silliness.

Riders reportedly also went pant-less on subways in Atlanta, Chicago, Dallas, London and elsewhere on Sunday.

A similar stunt in Moscow is being investigated by police as a possible crime.
