We put this movie on during our Halloween party and I mostly ignored it until I happened to look over at the TV and saw a floating head bite someone's butt or something and started laughing hysterically. I think people were more scared of me than anything else.
Hausu is pretty fantastic for “wtf” scenes like that one—but wait, that’s the only scene that caught your attention? Were you the only one laughing at that part? If so, I think you need new friends. ;-)
