Today I was watching The Nightmare Before Christmas for the first time in some years (the DVD is nice... but I digress), and towards the middle of the movie, there is a part where the undead Mad Scientist type flips open the top of his skull like it's a lid or something, and scratches or rubs his brain in confusion.
At that point I had a rather unsettling thought.
It started with idle speculation about how it would feel to just lightly run your hand over the surface of your brain, assuming that it could be done in relative safety. Would you feel a tingling sensation? Maybe a crawling feeling down your spine?
That's when the disturbing part hit me.
What if, in the course of this hypothetical brain massage, you accidentally touched the part of your brain that controlled the muscle movements in your hand and arm? Suddenly that light touch causes your fingers to uncontrollably plunge deep inside your brain, instantly killing or at least horribly incapacitating you.
I suppose the logical conclusion to make is simply, don't touch your brain. If you absolutely can't resist the temptation, have a friend do it.
make sure they wash their hands!
