Some Philadelphia subway riders are gearing up to show some skin despite the Arctic temperatures, as the city readies for the annual "No Pants'' ride.
At 2:30 p.m., participants will meet at the Clothespin statue at 15th and Market Streets on Sunday before taking the ride.
What started in New York City in 2002 with a just a handful of people has blossomed into a worldwide movement involving thousands. No Pants rides are scheduled Sunday in about 50 cities across the U.S., Canada, Europe and Australia.
The event was started by Improv Everywhere, a comedy collective that stages unexpected performances in public places.
The goal is not to offend, but to make people laugh.
Philadelphia's version is sponsored by a laundry delivery service, and they ask folks to bring an article of clothing to donate.
Sunday's highs are in the low 20s, but it will feel more like single digits.
