My adenoids, 4 wisdom teeth, and one front tooth that was lying down sideways so that it would never come up. I still have the baby tooth in that spot.
I also had one eardrum removed and the doctor rebuilt it with extra tissue from the back of my head.
A few teeth (including wisdom), appendix, gall bladder, a benign tumor on my wrist, and uterus. I tend to get rid of a useless part every 10 years or so. (I don't count teeth)
One wisdom tooth, my appendix, cartilidge in my knee and my left knee cap. Saffron, you're the only other person I've ever heard of missing a knee cap. Feels much better now.
Wow - I might be the one missing the MOST parts: 4 wisdom teeth, right breast + 9 lymph nodes, ALL my female parts, part of my thoracic spine (T-5)-- I was missing all my hair, but darn it came back !!
