    Or, when I had laughing gas during a dental procedure in my teens, it licks the dentist's fingers the entire time. I'm still not sure who felt more weird about that afterward -- him or me.

    An anatomical diagram of the human body showing labeled internal organs and disturbing facts about the human body. The intestines are covered by a double "fleece" of peritoneum. See it like a blanket. When your intestines get damaged for whatever reason, this blanket starts moving out of itself and crawling upwards towards the place which has the injury. It will stay there until the injury is recovered. And then move on again. Maybe not the most creepy fact, but definitely interesting in my opinion.
