my life quota of dismembered penises
Apparently, that roughly translates to uh, one.
Just having wrapped up Teeth (www.teeththemovie.com) I think I can safely say that it is not a movie for date rapists or those with any kind of blood squeamishness. Very funny and over all, not a well-made or well-realized vision, but well worth it for anyone who's ever fought off an overly-handsy drunken douchbag.
I give it four lamprey teeth for clumsy feminism, high-handed Greek mythology references and 3, count em 3, dismembered penises.
