Not quite as annoying as SantaCon (but still annoying), Improv Everywhere’s No-Pants Subway Ride plans its twelfth installment this Sunday. And unlike this year’s SantaCon, which was tempered somewhat thanks to heavy snowfall, the weather will be much better for going pantsless. Weather Underground calls for a high of 50, which, while not exactly sunbathing weather, is fine for going half nude inside a train. Last year saw 4,000 people participate here in New York, according to IE’s website. Seems like even more bare legs are in the forecast this Sunday, like it or not.
