Chop 'til You Drop

She's having psychotic attacks
and chopping off heads with an ax

Since Joan's been released

the death rate's increased
and heads have been piling in stacks

Recently released nutcase Joan Crawford is soon wielding a bloody ax in director William Castle's uncharacteristically gimmick-free shock-fest, Straight-jacket (1964). One of several films that followed in Psycho's bloody footprints that were written by Psycho author Robert Bloch.
