several (more than 3) full frontal nudity shots of grown men. The nudity is incidental and not the the focus of the scene; they all occur during skinny dipping scenes. There is also a scene of Jason Alexander wearing an apron and nothing else.

There's plenty. Of all varieties.

There is a particularly emotionally disturbing scene when one of the characters receives horrible news and appears to be in the worst pain possible for an uncomfortable amount of time.
