Not Always Right has the story of a poor woman who unwittingly rented an unrated movie she was unfamiliar with for her young son's sleepover, and ended up apologizing to the parents. She calls the rental place for advice on how to avoid this in the future, who advised her to read the label. Her comment was, "Yeah, I know, I read it. It says, 'Nudity, Strong Sexual Content, Drug Use, and Adult Language.' EVERY movie has that."
I think I see the problem.
