No Pants Subway Ride

[2] Beginning in New York in 2002, the event had spread to as many as sixty cities as of 2013[update].

[2] The event is organized by Improv Everywhere, and has coordinators in cities around the world.

The participants were investigated by the police under the offense of the "instigating of mass public disorder", however there are opinions the accusations would not stand ground, since the organizers' goal was to make people laugh.

[6] In January 2018, The Guardian published a photo montage of participants in the subways of some of the sixty cities worldwide, calling the event, "International No Pants Day".

[7] Celebrations in 2021 and following years were cancelled due to the COVID-19 Pandemic,[8] but were resumed in 2025,[9] though apparently not in New York.
