If you have not heard of Improv Everywhere, then you must be new to the internet, and welcome.

What’s more likely is that you have heard of the New York pranksters and seen their videos. You probably also know of their wonderful group pranks, and possibly even participated in the MP3 bit back in October. Now you can join in another one with No Pants 2009. This is where a flash mob of folks in Chicago, New York, and other public transportation blessed cities will ride the (in our case) the El without any pants.

Full details are available at the No Pants subway ride Chicago Facebook group. Basically, show up at the Granville station this Saturday January 10th at noon wearing pants (don’t forget the undies!). Instructions will be given out from there, but the whole point is to look like you have no idea that you walked out of the house without your pants. To inspire you, here is an old cartoon promo discussing pants vs. no pants:
