The Headcrusher

Chin is positioned to the lower bar
Whereupon the cap is made to put on
Down by means of the screw
The headcrusher is used on you
The caps are furnished with soft material pads
In order to leave no mark on your head
Teeth are crushed into their sockets
And the surrounding bone is smashed
Until the brain is forced out
Through the fragmented skull
Just a few turns of the screw
Are sufficient to make you do what I want you to do
