If We Did It This Way, I Guess Bush Would Be Mr. America

A strange factoid:

The British Royal family don't really have surnames.

Well, they do have a surname (Mountbatten-Windsor), but the usage of their surname is strange enough that Prince Henry, who recently joined the British Army, will come to be referred to as Mr. Wales, Officer Cadet Wales, or simply Wales.

Henry Charles Albert David Mountbatten-Windsor's formal title is His Royal Highness Prince Henry of Wales.
