No pants? No Problem!
Well, at least it's not a big deal during the annual No Pants Subway Ride, which took place in cities around the country Sunday.
And, yes, participants strip down to their underwear, despite many cities like Chicago, Boston, New York and Washington, D.C. facing below-freezing temperatures.
But, hey, that didn't seem to stop people.

The annual event is organized by the
Improv Everywhere comedy collective. The organization started the event in New York in 2002 when it had just seven participants.
Participants are instructed to casually get on trains and are assigned a location to take off their pants.
What's even more difficult? They are asked to keep a straight face while stripping down to their underwear in front of complete strangers.
