My sister (a doctor) told us of a few rather unsavory incidents that happened with body parts during her time at medical school.

Its pretty common tbh.

Yikes! I hope that was a corner, nee coroner, case, but it would not surprise me. My mother was a student nurse in the 40's. In the U.S. for context. She told me of corpses floating in a big tub, or vat, at uni, and that they had to take them out and dissect them for class. She didn't mention any peculiar schenanigans as you describe and I am glad she did not.

shenanigans (no "c").

Good catch. Thank you.
