Tyler Nilson appears completely naked and features frontal nudity. We see his cut dick and butt first in close-up as he stands next to John C. Reilly. We know it's not a stunt as we see him again from further away later in the scene. We see later John C. Reilly naked but it's obvious that the butt shots are stunt. A nice butt but we don't know who to give the credits to!
