History of No Pants Day
A small campus club at the University of Texas in Austin known as the Knighthood of Buh thought that dropping trousers on the first Friday of May was a humorous stunt for the end of the semester. Informal for years, promotion efforts began in 2000. The event attracted attention in other states and several parts of Canada as well as France, Sweden, Australia, Finland, and the United Kingdom.
