An event that occurs every Friday, regardless of weather, where everyone is required to leave their pants at home for the day. The origins of No Pants Friday (NPF) can be traced back to a cold Canberra night (or two) at Nightsbridge, and first afflicted a group of hearty ANU students. The phenomenon spread like wildfire through the Chemistry department, eventually taking the Fenner school with it. With each Friday, the word spread and more and more men and women join in the NPF festivities.
