My mother still has both my foreskin and a piece of my umbilical cord. They’re in a robins-egg blue shoe box. She showed 'em off when my wife and I visited maybe a year ago. My wife thought it was cute.
I assume my mom still has the same items from my brother, but I pointedly did not ask to see them.
Huh… that’s surprising. The birth center my wife and I were using was going to allow us to keep our last daughter’s placenta. When we wound up having to go to the hospital after all, they were still cool about it and let us keep it. They even boxed it up very securely in a thick plastic container for us, sort of like Tupperware.
We buried it in the ground (deep), and planted a small tree over it. It’s my favorite feature of the front yard, even though the Japanese maple overshadows it quite a bit.
I had a large (10 lb) cyst removed - My husband wanted to keep it (ick) but it had to be tested. Thank Og!
Then I had a Kidney Stone - They lasered it out and showed that to him but said it was all in little pieces.
My mom went in for an angiogram, and the doctor came out to the waiting room to tell use the news and that she was ok but they found a blockage. I’m nosy so I asked where and how big, etc. Doc got real excited and took the whole family back to the operating room so we could watch the x-ray video of it. It was so funny - “ok this is the entry…fast forward… this is important… OOOO this is good!” He was so happy to have someone interested in the actual procedure!!
Too bad you threw it out; maybe you could have re-hydrated it and had it sewn back on (JDT? You listening?) 
Mine isn’t really that interesting after seeing some of the others, but I have still got the screws that were in my leg for a year, after fracturing my femur.
When I was in seventh grade, I broke both bones in my arm and had to have a titanium rod put in. After a few months, they took it out and I got to keep it. My dad attached it to a cylindrical piece of wood and now I use it to roast marshmallows. People always ask me if I washed it beforehand, and I say that I sure didn’t, but hopefully the hospital did because there was no blood on it. 
My dad still has the bullet which caused him to be brought home early from Vietnam. No, I remember now, it was stolen last year (stupid bastard kids).
My husband won’t throw away the spine from a snapper fin which became embedded in his finger nine years ago.
I have my son’s baby teeth (the other two kids haven’t lost any teeth yet).
Japanese tradition is to keep the bit of umbilical cord which falls off the baby after about a week. The hospital gives you a little box to keep it in and everything. My son wanted to see it the other day, but was really disappointed to see it was so small. I think he was hoping I’d have the whole cord. He’s lucky I have it at all; I actually threw it out, but managed to retrieve it from the rubbish bin when my MIL had a fit.
Hey all. I’ve been away for awhile and am glad to see that placentas have been quite a popular topic. In any case, in our baby class of 8 mothers, 4 were planning on keeping it. A 50% rate! Kind of high I thought, but it was in Santa Cruz after all. Two of the mothers were planning on burying it and planting a tree over it while the other two were both planning on ingesting it - one as a a quiche and the other as tea!
