I found an AP article about a guy on death row down in Texas. Apparently in 2004 he killed his two young children and his estranged wife by cutting out their hearts, putting them in his pocket, and then stabbed himself before he walked into the police station. Needless to say he was found guilty. A few months before his sentence was handed down he “plucked out his right eye”… only to be found competent to stand trial.
Fast forward five years. He’s now decided that he needed to remove is other eye… this time he ate it. Now, apparently they are finding him insane and shipping him off to a psychiatric facility.
So, the lesson here would be that if you remove one of your eyes your completely sane but if you remove them both and consume them that makes you crazy. Leave it to Texas.

Eww…
You would think the heart-cutting-out thing would have made them question his sanity.
