One time I had a pin through my hand. A medical pin. I broke the growth plate in my left hand's thumb. There was a cast. The cast came off, and when it was time to remove the pin, it was awesome. I have a policy of watching. The "pin" slid out. Apparently pins are long, and they extend from the entry point to the other side of the hand across the bones. Woah. What a trip. Blood came up and poured over the hole. When the pin was removed it felt like an orgasm in my tummy.
