I used to have a 1920’s chemistry typewriter. The top row had only numbers on all but one of the keys- the other was a yields arrow. When shifted, the numbers were subscripted. Lost it in a move, somehow.
I have a five-peso bill that says, in English, The Japanese Government from the Philippines, WWII.
What? No love for my A-7E ejection seat? 
I was young, and it was when Heavy Metal magazine and such were very popular. I found a skull in the desert and thought it would be cool to have. I burned candles on it to cover it with wax.
A little plastic box containing an entire grotty decayed molar, complete with roots. I had a handful of daughter’s baby teeth, but they all crumbled up into bits over the years. ???
A 12" high Elvis doll dressed in black leather.
A white china trinket box with little flowers painted on, trimmed with gold. The removable lid has, for some reason, a handle shaped like a fish, painted black. ???
No goat skull, alas, though I found some kind of rodent skull (mouse? rat? some kind of mole?) in the park across the street.
An ancient, nearly empty bottle of Mitsouko perfume. I’ve been offered serious money for that bottle.
I’m pretty sure I have a mostly-empty bottle of dad’s Hai Karate around here somewhere.
A module from a vacuum-tube computer. Somewhere, someone else’s wisdom tooth that had been used as a Christmas tree ornament.
Most bizarre? Probably the piece of melted glass from Belsen - they burned the whole place down after liberation because it was just too riddled with disease to be reused the way e.g. Dachau was.
I keep finding 17th/18th century clay pipe stems in my coat pockets. You can pick them up by the dozen, along with similar age oyster shells, by the river. They’re not special or rare, but I apparently can’t stop myself from picking them up, sticking them in my pockets and forgetting about them.
I still use the mobile phone I got in 2002. That’s got to be bizarre!
I HAD an 8-oz bottle of laboratory grade Trinitrotoluene (TNT). I found it when I moved into this house. I kept it around thinking it was kind of neat to have. I was going to try to make some firecrackers out of it, then common sense kicked in.
FYI… the trick ‘n’ treaters as well as the door to door salespeople do not knock on the door much anymore.
I’m feeling pretty deprived for not having a goat skull.
I used to have a big fiberglass carrier some sort of missile warhead (I originallly used it as the base of an end table) that I’d picked up at a garage sale, but within about six months of getting it, I started wondering how the hell I would ever be able to throw it out without alarming the next person to cast their gaze upon it, so I brought it (covered in a blanket) to a junkyard and gave it to them.
Currently, I have an X-Men #94 and a lead block used as shielding in the Cyclotron that lived at the University of Chicago. I also have a slide rule in basically new condition that I bought to actually use; my age cohort may have been the last to have been taught how to use a slide rule because we were supposed to need it. I still keep it around for when we have to rebuild civilization after the food riots caused by the lack of genetic diversity in our crops.
I’ve got a crude oi painting. Not a poorly executed acrylic artwork, but a painting where the artist utilized crude oil.
hm, I could arrange a sheep skull for you i think - last sheep we slaughtered one of the dogs grabbed the head and headed into the woods with it, mrAru reported that the skull was still knocking around in the woods last year. i would have to send him back out to check …
I have a flak jacket which is like a military bullet-proof vest but much thicker and heavier with some neck protection against other explosive devices like grenades. It must weigh 12 pounds alone. My father bought it for me at a gun show when I was in high school for my birthday. That isn’t so unusual I think but I have moved around a lot and I don’t have many things with me from when I was young. My flak jacket is a constant and I have kept it in the back seat of every vehicle I have ever had in the past 20 years. The model is a little too small for me now but it is adjustable so it can still do the job in a pinch. I don’t usually drive people around other than family members, but when I do, they often ask me why I have a bullet-proof vest with me. I just say that life is like a box of chocolates and let it go. I think everyone should have one though.
I have a hunk of graphite used in the first nuclear reactor (under the old football stadium there)…those were the days.
i almost forgot, I also have what I believe to be the world’s first and (until I built a couple for my roommates at the time) only graphite composite necktie.
It is worn by rubber bands under my collar and being stiff as a (actually quite a bit more than) board, tends to catch on my shirt or pants and deal a hard blow to my Adam’s apple. Despite looking cool I doubt that it will catch on.
Oh! And I have a book signed by one of the creators of living unicorn-goats.
Though, in all honesty, I didn’t remember who the author was at the time…or realize that it was signed. Actually, I think that makes it a little more bizarre on my part.
Full sized anatomy skeleton
6 foot tall suit of armor (can not be worn)
2 foot tall statue solid brass statue of Shiva
Miniature carousel horse (maybe 4 feet tall, pole included)
I would have had a phone booth, and an old Pepsi machine from the 60’s, but couldn’t find anyone willing to let me use their truck.
The Nimitz thread reminded me that I have a 100-pound practice bomb. Recently I thought about getting another one, but they’re getting a bit pricey. Mine is marked $19.95, and I got it in a surplus store in Lancaster about 25 years ago.
Just a side note – I believe some posters to this thread have confused “bizarre” with “unusual and cool”. For me, a possession does not qualify as 'bizarre" unless normal people would entertain real doubts about having it in their house. I’d say most of the stuff mentioned so far falls under that description, but there’s a certain percentage that does not.
Carry on…
Well, I think my mother tossed out the collection of cat eyeballs and testicles awhile back. A pity—they looked nice on the spice rack.
