Inspired by @chrisgill. Draftmas #4.
  1. Period cramps.
    Unlike some of my friends I've never actually blacked out from these, but there have been several times where I came close.
  2. Trying to walk on the ankle I had just broken so that I wouldn't look like a fool to the crowd of people whose help I had rejected when I fell off an 18-inch rock.
    Definitely showed them by giving up after one step and trying to crawl back to the car.
  3. Getting anesthesia shots to remove ingrown toenails (multiple incidents, each more painful than the last because I knew what I was getting into).
