The weirdest thing that Fisk and I did on our trip to Paris was check out this museum of medical oddities and malformations. The museum was within a medical school in Paris, so we had to navigate the campus in order to find it. When we found it, we bought our tickets, walked past stacks and stacks of dusty books before reaching an open room with row after row of medical strangeness. It was pretty rad/interesting.
These photos are not ones I took, they didn't allow photos in the museum, but google had plenty of images. All in all, this museum seemed like an incredible resource for medical students, even though it was pretty creepy to see deformities housed like this.
