I saw where a new movie titled “Teeth” is being released.  Apparently, the plot revolves around some girl having teeth in her, uh, private parts.  And, taking it a bit further, she’s able to do some damage to males who sexually abuse her.  Well, this premise is an idea ripped-off from a book: Black Body by H. C. Turk.  I read the book way back in 1992 right after it was published.  The movie producers have simply brought the idea into modern times rather than relying on the original story.
