Inspired by the success of their recent X Marks your Spot campaign (featuring Kellan Lutz, Hidetoshi Nakata, Fernando Verdasco and Mehcad Brooks) Calvin Klein has decided to take the ad campaign global and has launched X Marks your world. X Marks Your World gives guys around the world the opportunity to upload a video of themselves wearing Calvin Klein underwear to youtube and get them featured as part of the X Marks The World project.

P.S having the body of a Greek God will give you a better chance of being featured .
