I’m sure you may have some weird jobs stories out there, but I think I may have most of them all beat. For about two years I worked in a biological lab where we received daily shipments of human umbilical cords from hospitals all over the country. We would mount the cords onto glass rods and soak them for several days in gluteralderhyde to tan them like leather. Once tanned, we would use forceps to remove the veins. Then we would turn them into bio-grafts to be used as replacement arteries in humans.
If you’ve had a stranger job than that I’d like to hear about it.
