After 10 years of the annual "No Pants" BART Ride, we're not entirely sure we consider the event improvisation anymore, but it's still loosely related to flashmob enthusiasts Improv Everywhere so we suppose we'll allow it. Anyone interested in kicking off their britches along with a couple hundred of Bay Area Rapid Transit's most whimsical riders would do well to make their way to Powell Street Station at 2:10 p.m. this Sunday afternoon or follow NoPantsSF on twitter for pants-free updates.

As a friend once pointed out, these types of things tend to be for the enjoyment of people other than those at the actual event (like those of you leering at the photos later), so just keep that in mind when you're standing on a train without your pants on. Wear fun underoos, at least.
