According to this BBC news report, a senior Iranian cleric (so you know it must be true!) claims that immodestly dressed women cause earthquakes.
Presumably it's the earth moving while they're all crazily committing adultery that does it.
Hojatoleslam Kazem Sedighi told worshippers in Tehran last Friday that they had to stick to strict codes of modesty to protect themselves.
"Many women who do not dress modestly lead young men astray and spread adultery in society which increases earthquakes," he said.
The initial response is to lie on the floor howling with uncontrollable laughter, but then it gets altogether more depressing when you realise how many people there are in the world who believe such idiocy and much in the same ilk.
Some even live in our own country, IPU* help us!
