Human craziness is infinite.
Not really a Darwin (however it could be) but what I was laughing for weeks was a pig slaughter story. The guy wanted to let his floyd slaughter and called for the pigsticker of the village. Both washed hands, etc etc and went to kill the pig. Unfortunately the pigsticker slipped while he tried to catch the floyd...he touched himself with the electric shocker (or how's it called...), got an electric shock and died. The floyd owner saw it, but he was so surprized that he got a heartattack and also died in some minutes.
So only the pig survived.
Annnnd the wife of the man kept the floyd because she said, "it reminds me to my husband".
