In South Africa, a man shot his pregnant fiance then killed himself. They're still getting married.
As bizarre as this is, a few years back in Northern Kentucky, a man dead for two years was awarded a divorce from his widow. Let me see if I can google that up.
Update: Here's the story of the dead man's divorce. Hey, a new variation to the old joke: if a dead man divorces his wife in Kentucky, are they still brother and sister?
