Recently, I saw this film, Teeth. Looking at the poster I thought that it might be a comedy or something, but not quite. It's about this girl discovering that she has got Vagina dentata is Latin for toothed vagina. ( [link] )
Anyways, if us women has these teeth in us and we can control them, there will be a lot lesser penises in the world. No? >3>;
