Mark your calendars, kids, because this Sunday is No-Pants Sunday.

Huh?

It means a wacky group of improvilicious New Yorkers will descend upon an unsuspecting IRT Sunday afternoon, and, in a series of steps apparently choreographed with Busby Berkeley-esque precision, they'll remove their pants and then ride the 6 as though nothing is out of the ordinary.

These seems an excellent opportunity for exhibitionists and voyeurs alike, which makes it a good thing. But we also don't see what's quite so special about it. It just happens the once, and just on one subway train, which makes No-Pants Sunday, best we can tell, not terribly unlike any other Sunday.

If they knew how to zap away, Eternal Sunshine-style, all recollection of the pants-free folks we've previously encountered on the subway, well, now that would be special.
