The No Pants Day is a participatory annual event that has
happened in various nations on the first Friday in May. It requires
wearing just undergarments in the lower part of body, in public.
A small on-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
