The No Pants Subway Ride is an annual event staged by Improv Everywhere every January in New York City. (The date changes from year to year and is announced in early December.) The mission started as a small prank with seven guys and has grown into an international celebration of silliness, with dozens of cities around the world participating each year.

The idea behind No Pants is simple: Random passengers board a subway car at separate stops in the middle of winter without pants. The participants behave as if they do not know each other, and they all wear winter coats, hats, scarves, and gloves. The only unusual thing is their lack of pants.

Here’s a video telling the story of the very first No Pants Subway Ride:

Below is an overview of the history of The No Pants Subway Ride dating back to its inception in 2002.

No Pants Subway Ride 2009

The eighth annual No Pants ride had 1,200 participants in New York and well over 1,000 more in 21 other cities across the globe. The New York ride took place during a snow storm (a first) and was carried out on four train lines.

No Pants Subway Ride 2008

The seventh annual No Pants ride had 900 participants in New York and was the first year to go international, with 9 cities joining the fun. In New York we had to use three separate train lines to accommodate the crowd. For the first time there were at least as many women as men. This was the first year we invited other cities to participate as well. Rides took place in Baltimore, Boston, Chicago, Portland, San Francisco, Salt Lake City, Toronto, Washington DC, and even Adelaide, Australia. The Today show even mentioned the event: video.

No Pants Subway Ride 2007

In sharp contrast to the year before (see below), the sixth annual No Pants went off without a hitch. 300 people participated on what was a particularly mild January day. Three police officers showed up at our meeting point, but they informed us they were only there to make sure everyone had a good time. We dropped the “pants seller” bit this year after too many people lost their pants in 2006. Instead, participants hid their pants in a backpack. This was the first year No Pants really started becoming diverse, with people of all colors, shapes, sizes, and ages participating.

No Pants Subway Ride 2006

The fifth annual No Pants ride was abruptly halted by a cop. All passengers, including those not participating, were forced to exit the train as it was taken out of service. 8 people were handcuffed in their underwear and taken into custody. A month later a judge dismissed all of the charges. It is not illegal to wear your underwear in public in New York City. Just ask the Naked Cowboy. The incident was reported by news agencies around the world. David Letterman made two monologue jokes, about it and staged a No Pants Cab Ride as a parody. Keith Olbermann interviewed Agent Todd about the legality of No Pants. Around 150 people participated in the ride.

No Pants Subway Ride 2005

The fourth No Pants was filmed by This American Life for their Showtime television show. The segment on Improv Everywhere aired as part of their pilot episode, but almost all of the No Pants footage was cut from the piece. We didn’t film it ourselves, so no video exists. Around 50 people participated.

No Pants Subway Ride 2004

The third No Pants was filmed by ABC News 20/20 for a segment they were doing on Improv Everywhere which never aired. Bill Ritter, a 20/20 correspondent, rode the train with us but elected to keep his pants on. About 40 people participated. We did not film it ourselves.

No Pants Subway Ride 2003

The second No Pants had around 30 participants, including a few women. A few people played characters for the first time– businessmen, tourists, etc. The conductor noticed what was going on and shouted over the PA, “This train is not a playground.” There is video footage, but it has never been put online. Maybe one day.

No Pants Subway Ride 2002

The first ride included 7 participants, all male. One participant entered the train pantless for 7 consecutive stops. They pretended not to notice each other, and if asked claimed that they “just forgot” their pants. On the 8th stop, someone came through with a duffle bag selling pants for $1. No photographs were taken, but the above video was captured with our single a hidden camera.
