[Dr. Boogie]

Years ago, I was having an argument with my sister in her room. At the end of it, I walked out, and she slammed the door on the tip of my middle finger. Cut the top quarter-inch almost completely off, and yanked the fingernail out. Not a fun time, but it was interesting watching the exposed flesh slowly dry up and fall away as the newer, thicker fingernail grew up under it.
