Things got a little nippy during this sledding competition in Germany. Male and female participants alike went topless for the event held in front of a crowd of more than 17,000 people. Despite freezing temperatures, teams were clad only in helmets and briefs to battle it out for the prize of $1,600 and the title of Naked Sledding World Champion. "It's a very closely fought contest which is good for us because we're all very keen on studying the photo finishes," one judge said. The winners this year were three workers from a local hotel. They may have been cold, but all those watching must have been feeling pretty hot.
