In this TV show, Mark-Paul Gosselaar shows us some skin in the pilot. He is naked in a hot tub, when a friend asks for him. He gets out of the hot tub, and the camera spends a good amount of time filming his butt. A nice butt! Good job Mark-Paul! Hopefully more skin and a frontal from him soon! Mark-Paul is known to be uncut, but we would like to make sure!
