Lazarus and Joannes Baptista Colloredo
http://en.wikipedia.org/wiki/Lazarus_and_Joannes_Baptista_Colloredo
This pair came up in my history of science lecture the other day, 17th century conjoined twins who toured all over Europe. Wikipedia reckons they lived for over 29 years. Crazy shit.
More of this kind of thing.
