Artificial Anus
"A 78-year-old German woman went into the hospital last month to have surgery on her leg. Because of a mixup, Frankenpost reports that she left the Hochfranken-Klinik in Münchberg, Germany, with an artificial anus."
That's no fun.
So I suppose the next time you think you're having a bad day, you need to remember you could have been accidentally implanted with an artificial anus.
