Bizarro is brought to you today by Dubious Parades.
I remember visiting a museum years ago – can't remember which one or where, which is one of the problems of traveling a lot – wherein there was a display describing prehistoric surgery. For reals.
Apparently, somebody (anthropologists? archeologists? utility workers?) found ancient skeletons from cave man times that have pretty clear evidence that their skull had been cut into then sealed again while they were alive. I suppose scientific curiosity is a possible motive but that aside, I have to wonder what they were trying to cure. How aberrant can a caveman's behavior be that his friends decide they might be able to fix it by digging around in his head? If he was killing people for no reason, seems more logical that they'd just kill him. If he was hallucinating, they'd likely chalk it up to a spiritual experience. Same with epilepsy or whatever. Maybe he was the first person to start talking and they thought he was crazy. It's interesting that they even suspected that fiddling with the goo inside your head might change something about your life.
If anyone knows more about this, let me know. I don't have time to research it this week, I'm trying to get ahead on deadlines so I can take a little vacation. Even if you just have a theory, leave it in the comments. I find this kind of thing pretty fascinating.
