The No Pants Subway Ride 2010 edition took to the TTC yesterday. Organized by Improv in Toronto, the bare-legged, goosebump-generating "flash mob" experience sees riders casually whip off their pants, revealing their tighty-whiteys, bikini briefs, lacy panties, and boxers... and take the train - much to the awe/delight/fright of unsuspecting passengers.

blogTO contributor Paul Flynn happened upon a number of pantless participants taking part in the 3rd annual winter event, and sent us a link to some photos he took. blogTO Flickr pooler SasiShan also dropped a few in our pool this morning. Looks like a lot of (shivering) fun, doesn't it?

The phenomenon has become a worldwide event (see BBC video), with transit users in 43 cities taking part this year.

Update (January 15th): video!
