24. Fatal sex

In some cases, polygamy, although encouraged in some cultures, could prove disturbingly fatal. Take the case of Nigerian businessman Uroko Onoja who was notorious for being polygamous. He had six wives, the youngest being his favorite. The five wives became jealous when they caught Onoja sleeping with the younger woman. They demanded, at knife-point, that he sleep with them too. He had sex with four of the wives one by one but died before getting to the fifth one.
25. Killed by his own coffins

It was 1982 in France, an undertaker named Marc Bourjade was crushed to his death by a pile of caskets that fell on top of him. He was later buried in one of those coffins.
