Just goes to show, taking a Sharpie with you if you need surgery and WRITING ON VARIOUS PARTS OF YOUR BODY things like "NOT THIS ONE, DUMBASS!!!" "ONLY THE TIP YOU DUMB BASTARD" is a good idea.
Despite the fact that doctors like to think they are God, they can be dumber than dogshit and when they fuck up they never say "Sorry" they just blame someone, anyone, else.
