I doubt that was the name his mother gave him on the day of his birth... Regardless of what the standard verification processes would accept, I would want to see a birth certificate and a document legally changing his name.
You're absolutely right, I've never heard of such a thing so I would not be anxious to accept it. If it is for real, however, I think I've met him. He's a short guy who likes as much attention as he can get?
