What's necessity got to do with it?
I don't know if you ever saw the
body worlds exhibition, it freaked a lot of people out and received both acclaim and scorn. Dr von Hagens is a nutter, but better have him doing things like this in the name of medical science or art, otherwise he's most likely be lurking in a alley somewhere trying to chat you up.
I remember finding something like this in nottinghill about 12 years ago... if I remember correctly it was called the Dartmouth Devil... fascinating.
I'm going to stop before any of you think I stuff my cats or I've got a hippocrocapigadog at home.
