Interesting. I was under the impression that US citizens could not receive a MBE (Knighthood). Is he now Sir Fonz? :0)
Sir Arthur Fonzarelli to you, knave.
It's honorary, not a knighthood (so it isn't Sir Fonz), and only members of government are prevented from receiving foreign awards without Congressional approval.
MBE and OBE are not knighthoods.
Steven Spielberg was awarded the KBE, which is basically a knighthood (Knight of the British Empire) but doesn’t allow him to refer to himself as Sir Steven because he’s not British or from the Commonwealth
