HBO Family(?) Movie

The “Family” movie on HBO tonight is… Adam Sandler’s 8 Crazy Nights.

Is this some kind of joke?

Before the movie, a warning screen explained that it contains Violence, Adult Content and Adult Language.

IMDB says: Rated PG-13 for frequent crude and sexual humor, drinking and brief drug references.

A user review excerpt:
What we do have to contend with are defecating deer, some jock-strap consumption, port-a-potty tipping, belching and other assorted bodily functions, three-breasted women, and, incredibly enough, seizure jokes.

Please explain to me how that is a family movie!
