Over the last few months, New Yorkers may have been blessed with a sighting of The World's Fastest Nudist, a man sprinting through the city and its boroughs wearing little more than a fanny pack over his private parts. While giving the Naked Cowboy some stiff competition, he updated his escapades on his blog, built up a sizable following on YouTube and garnered attention from various media outlets. Turns out, the whole thing was a clever stunt via New York's Agent 16 and production outfit Bullet, to promote the fact that online shoe retailer Zappos.com also sells clothes.
