Mutter Museum: Plaster cast of Chang & Eng, the original "Siamese twins." Fun Fact: they married sisters and lived on two adjacent farms in the south once they left the circus. Between the two of them, they had 21 kids. I can't even imagine how the logistics of that sex worked!
Conjoined twins Giovanni and Giacomo Tocci (born either 1875 or 1877, death unknown). They were the inspiration for Mark Twain's short story "Those Extraordinary Twins". They couldn't walk, but could crawl or they used a wheelchair. They settled disputes among themselves with their fists (!). They retired from the sideshow in 1897 and bought a villa in Venice. They became recluses and strangely, their date of death is unknown, being reported numerous times between 1905 and 1940.
