So, on January 8th, 2012, Improv Everywhere will be doing their annual No Pants Subway Ride. "Undercover Agents" will board subway trains non-chalantly pantless. I wish I had more details to report, but that's basically all that's going to happen. People will get on subways pantless, arrive at their destination, and we assume, put their pants back on and carry on with their day. Which I guess is funny, except it's been going on for 11 years now and the jig is sorta up. Also, pretty sure your average subway rider isn't particularly interested in seeing exposed Chewbacca-like thighs or a stranger's BVD banana hammock all up in their face while stuck on a crowded Sunday train.
Any-who, if you're into that sorta thing, you can go here for details.
