The No Pants Subway Ride, which has somehow taken root and become an annual tradition that thousands participate in, is upon us once more. That's right, it's this Sunday, January 12th.

If you like exposing your legs and maybe a little bit of ass cheek to the general public, here's your chance. If you like seeing people's legs and maybe a little bit of their ass cheeks, here's your chance. If you don't like seeing people's legs and maybe a little bit of their ass cheeks, you should probably spring for a cab. If you like following said people silently and eventually getting up the nerve to suddenly slap an ass cheek, you're a sex offender.

It's not just in New York any more either, basically every city that doen't have draconian laws regarding this sort of thing is participating, even all the way up to cold-ass (quite literally) cities like Montreal and Stockholm.
