A teacher at Hampshire High School in West Virginia screened "Fifty Shades of Grey" in her classroom as a reward to her students for their good behavior.

When the teacher asked the kids what movie they wanted to see, the students said they would like to watch the controversial, R-rated film, which is known for explicit sex scenes involving bondage and sexual violence.

10 minutes into the screening, an assistant principal walked by the class and recognized the movie, shutting it off immediately.

The teacher claims she wasn’t familiar with the film's sexual subject matter. A disciplinary hearing will be held Monday night.
