How do you prove to a woman she is Beautiful?

A friend of mine and I were having a discussion the other night abo-ut how actions speak louder than words. So I came up with the question of, "Since actions speak louder than words, how does one PROVE to a woman that she is beautiful? Seeing as how the word is an adjective and not a verb how do you DO beautiful?" I have come up blank with the exception of that it has to be something tangible, physicial and out of the ordinary. Because any man can "say" a woman is beautiful, but to PROVE to a woman she is beautiful is something different entirely.
