My mom has told a story often about her time at West VA U (Morgantown, late 40s).
The school was proud of it's medical school, and made an opratory theater open to visitors.
So the med students are working on a cadaver with a full house, and one of them has put a bag of chipped ham down in the cadaver, and proceeds to eat handfuls of it from the cadaver.
Laughter from the students: shock, vomitus, and running from the visitors.
U officials, anxious for donations from alumni, insisted there would be no more eating from the cadavers.
Selling human body parts is not funny, or decent. Or lawful.
The parts available at the grocery store are all anyone needs.
