Take off your pants and ride the rails

Of course the annual No Pants Subway Ride falls on the coldest weekend of winter so far — it wouldn't be as fun otherwise! All you need to participate is two things: 1) willingness to take your pants off on the subway and 2) ability to keep a straight face about it. There's also an after-party at Lucha Cartel.

Where: Meet at the Clothespin at 15th & Market streets

When: January 8, 2017 at 2:30 p.m.

How much: Free
