This year, pro-pantsless participants gathered around 3pm at six locations throughout the five boroughs. Once divvied up into groups, the soon-to-be half naked New Yorkers made their way onto the subway.
Once the train doors closed, they removed their pants and maintained a straight face, as instructed.
If asked why they weren't wearing pants, they would simply reply, " I forgot".
