Aussielicious has issued a challenge on his blog to send him naked self-pictures taken in preferably in as-well-known-as-possible public locations. The series so far is quite riveting (if somewhat work unsafe) and my favourite is the guy who stripped off at the Queens Museum and Flushing Meadows Memorial.
I must think of a place to have my picture taken. Our nude beach really doesn't count because everyone is naked there so there is no challenge.
UPDATE: Thank you, Bloggreen, for the Andy Roddick pic reference. I better post it before the paper takes it offline. Playing nude tennis sure qualifies in my book!
