Note: Uncensored shot after the jump because I'm a firm believer that nobody on the internet should be able to make you vomit without warning.
This is a shot of a man with a rare condition called cutis verticus gyrata. It causes folds in your scalp, which start to resemble a brain. This isn't even the most extreme example -- I made the mistake of Googling the condition and there are some much, MUCH more intense pictures out there. I don't suggest looking at them. I know I typically operate with a "If I had to see it, so do you" policy, so consider this an early Christmas present. Now, let's all take a moment to be thankful we don't have this. Or mini-peens.
Hit the jump for the brainier looking shot.
Thanks to Evil Ares, who's so evil he decided to share this with us.
