Ever seen Braindead? This guy gets his head ripped backwards, leaving his spinal cord and head sticking out from his lower back area (not his arse). He comes in and looks very frightning, then they rip out the spine and smash the head on the bench. BOOM! His head explodes.
Oh, right . . . then there was her awful series of Flying Head Christmas specials . . . Thank goodness she finally had that Broadway comeback, in Hedda Gabler.
