The "Unusual" Reasons Fifty Shades of Grey Just Earned an R-Rating

Prepare to hide your shock: Fifty Shades of Grey has received an R rating from the Motion Picture Association of America. Why? Because of the movie's "strong sexual content including dialogue, some unusual behavior and graphic nudity, and for language." We expected all of these, but "unusual behavior"? What might that refer to? It's very likely the S&M stuff, but what a weird way to describe it. While this rating isn't surprising, it will be interesting to see if the lack of a PG-13 rating will affect ticket sales. If you haven't already, listen to the newest addition to the movie's soundtrack, and check out everything else you need to know.
