Sword in the Stone

My friend came up with the best metaphor to describe an extremely attractive woman. We were talking about the stunning Zoe Deschanel and how beautiful she was, when my friend turns to us and says, "You know the old English legend of Arthur, where who ever can pull the sword from the stone will be king. Well, anyone who can pull my sword from that stone must be crownded king." We now use that term to describe only the most beautiful women, instead of asking, "would you..?", we know just say, "Sword in the Stone".
