When you get a chance, take a look at a photo of an orbitoclast (think ice pick). Hammer it in behind the eye socket, give it a good whack, and swing it around a bit. Walter Freeman, the asshole who invented the device, used to drive around the country in his little van performing lobotomies for $25 a pop. He had a nasty tendency to kill his patients; he even killed one when he stopped to have his photo taken with the pick in the patient's brain and accidentally rammed it in a bit too far. These things, of course, happen when you can't see what you're doing.
