Or maybe his fans have. In the pic, Gosselaar and animator Ben Ceccarelli are buck naked as they lean against the wall upside down. They have their hands firmly placed on the ground and are showing off every muscle of their body. A Photoshopped black line is also strategically covering their private parts. "Team Cocky," they named themselves.
