No Pants Day is a prank that some groups have made into an annual event, happening on the first Friday in May. The prank is based on the premise of having people attend an event not wearing any pants . Participants are challenged to act as if there is nothing strange about not wearing pants in public. The liberation of breaking a social taboo and seeing the reaction of people not aware of the event generally makes the event fun for its participants. Different groups celebrate it on different days of the year.
There are unconfirmed reports that No Pants Day was first celebrated as early as 1985 or 1986.
TexasThe Knighthood of BUH at the University of Texas at Austin are advocates of the holiday. Austin has celebrated the day since 1997 according to a 1999 flyer.

A version of No Pants Day is The No Pants Subway Ride, an annual event organized by New York City prank collective Improv Everywhere. In this event, members of the group enter a subway car at consecutive stops without pants in the middle of winter. Participants pretend that they do not know each other and if asked, claim that they simply "forgot" their pants. The first No Pants Subway Ride took place in 2002 with seven riders and has grown since then. In 2009 over 1,200 people participated in New York and over 1,000 more participated in 21 other cities around the world. The fact that the No Pants Subway Ride has become a global event with multiple cities participating on the same day has led to its confusion with No Pants Day.The No Pants Subway Ride celebrated in Second Friday in January.
