Four wisdom teeth, all the root pulp from a different tooth, bits of my nasal septum, adenoids, couple chunks of me vas deferens, foreskin.
Missing in action -
Wisdom teeth, one right rear molar (root canal replaced with crown) left big toenail, foreskin, lens in left eye (childhood accident - looks fine cosmetically), full head of hair (genetics) -
Two chunks of flesh-- one on my back, one on my cheek–that were playing host to melanoma cells.
It started out fun, went to interesting, progressed to sad, horrific, ghoulish, and then to TMI overload.
*runs away crying ‘someone help those poor, poor people!’ *
Mine didn’t start coming in till I was about twenty-four, and even now, I only have two and a half–one was pulled, two are fully out, and one is apparently only going to come out halfway.
I no longer have a gall bladder, but it was holding me back.
Hokkaido Brit, I’m not inclined to count the nail tips, as they keep growing back.
Lots of teeth, appendix in 7th grade, tonsils (it was automatic when I was born, out they came sometime after the first birthday). And that’s all.
4 wisdom teeth.
4 adult teeth (orthidontia prep).
A section of my parotid gland (tumor, benign).
1 foreskin.
Periodic haircuts.
Also, some of my naivete was carted away a while back.
But how would falling or being smacked around cause an entire rib to disappear?
Oh my. I forgot a little piece the the skin and cartilage of my left ear.
Just tonsils and wisdom teeth. And I was born with a ball of pus in my ear, which broke when I was about four years old, so I’ve got a hole where that was. It’s more like an extra cavern, really - it doesn’t go all the way through, and you have to be really looking in my ear to see it.
I cross my fingers that it stays that way for a long time!
Hm… still have my wisdom teeth. They’ve all come through my gums already and act as functional teeth. I am, however, missing that tooth behind your canines on top, on both sides. I am also missing an appendix. Sadly, I’m just not as cool as everyone else.
Shoulda previewed, though I can’t say for sure whether it would have made a difference or not. I added the thing about the ball of pus after I wrote the last line, but it makes it look like I’m saying, “WOO! I hope I get to keep my extra ear cavern FOREVER!” When in reality I don’t care at all. I meant I’ve lost all I want to lose at this point! Except ten pounds or so.
I’m a mellow guy
No spleen 
Then what do you vent?
Don’t ask.
Motorcycle accident, replaced with chrome steel.
I was born without six of my molars, four on the bottom and two on the top; i’ll probably have to get two more on the top taken off because they’re growing without any resistence from below, so it’s like i have fangs in the back of my mouth. I will, however, most likely not have wisdom teeth, since this lack of molars is common in my mom’s family, and few have had wisdom teeth; she likes to say it’s evolution in action.
Otherwise I’m intact. Tonsils, appendix, gall bladder, all there.
My aunt, though, is missing one of her pinky toes because my other aunt bit it off. Heh.
Ew. About five posts into reading this thread and I was all oooggglllly. I keep imagining all these body parts not connected to anything just floating around in the world somewhere.
Me–wisdom teeth, tonsils, about 5 pounds of breast tissue and a good hunk of my cervix (you asked).
Pork skin, 1966.
Appendix, 1975.
Pilonidal cyst, 1986. (Hey, it felt like a body part. Especially when it TMI TMI TMI.)
Wisdom teeth, 1997.
Several thousand crown and vertex hairs.
20 lbs of Reese’s Peanut Butter Cups.
A whole lotta beta cells.
