With half of the staff, and seemingly half of 360 and PC owners, enamored with Left 4 Dead, it's an absolute must that we let everyone know what become of that odd "Dude, Where's My Thumb?" contest developers Valve were running. The contest asked gamers to take a picture of themselves in front of one of their billboards in London, New York, Boston, Chicago, LA, Seattle or San Fran. The top 25 entries won a free copy of the game and the top winner, seen above, won a new gaming PC from AMD. Now about those tetanus shots.
