In cities around the world, from Sydney to Shanghai, people stripped off their trousers on Jan. 13 and rode subway systems fully clothed on top but wearing nothing on the bottom but their underwear. This was not a nudist protest or a case of everyone forgetting to do their laundry. It was the 12th annual edition of the “No Pants Subway Ride,” – an improvised comedy event started by the New York group “Improv Everywhere.”

Improv Everywhere organised their first “No Pants Subway Ride” in January 2002 on New York’s 6 train – the same line that this suspender-clad participant rode this year. The first pants-less ride started out with just seven people but since then the event has snowballed and this year thousands of people opted to take part in 62 cities around the world.

Improv Everywhere describe themselves as a “prank collective that causes scenes of chaos and joy in public places” - for example on the London Underground, where the no-pants event has been re-christened “No Trousers Tube Ride”.
Improv Everywhere’s founder Charlie Todd explained in a TED Talk lecture that his group wants “to cause a scene in a public place that is a positive experience for other people. It’s a prank, but it’s a prank that gives somebody a great story to tell.”
