This past Sunday the No Pants subway ride started by Improv Everywhere went global and there are photos from no pants [slightly NSFW] subway, lightrail, and tube rides from all over the world (and some from other worlds) on Flickr.
Photos from darango, Fred Dunn, SpecialKRB, Richard Walker Custom Bikes, nooccar, domichal, and bhautik joshi.
Lastly, well played sir!
