Here is a contender for the world's craziest name. It's Muhammad Cohen.
You may not be surprised to hear that film director Cohen was born Eliot. However, he changed his name following his marriage to an Indonesian Muslim woman in 2002. It was, he said to demonstrate the similarity of the Muslim and Jewish religions.
Cohen said he was welcomed by the Muslim community. When he decided to marry, the only worry of the officiating Imam was that he be circumcised. Cohen was able to re-assure him on that count.
