Photos from CTA No Pants Day 2017

The event is organized by the Improv Everywhere comedy collective. It started in 2002 in New York with seven participants.

Organizers say pants-less subway rides were scheduled to take place this year in dozens of cities around the world. Philadelphia’s version is sponsored by a laundry delivery service.Participants are told to get on trains and act as they normally would and are given an assigned point to take off their pants. They’re asked to keep a straight face and respond matter-of-factly to anyone who asks them if they’re cold.
