A little bit of a deviation from the high-def wallpapers, but I couldn't pass up this photo taken by Tyson Cecka that was in the July 7th POTW gallery.  The saying is one I'll never forget from when I saw it on a t-shirt at the first PKUSA in NY years ago. I believe it was Ductmonkey, the creator of PDQ, who was wearing it!
