Roses are red, violets are blue. . .will you marry me? *(a Rich-worthy blog)

Why is the universal symbol of marriage a wedding ring? I mean, sure, it looks pretty, and it looks nice on the "ring" finger, but wouldn't you think that there should be a bigger symbol for marriage? I mean, marriage is a BIG thing! It can completley change 3 lives: yours, your wifes, and her mom.
But anyways, I think that the wedding ring became the symbol of marriage because men everywhere (especially on the BYU campus) were getting tired of asking women out hearing the same answer:
"Oh, no thanks, I'm married"
Sometimes this were true; other times the men tried to use cheasy pick-up lines which allows the girl (its written in the bible somewhere) to blatently lie.
Not only that, but when a man has actually found a wife, he would not be comfortable with other men asking her out. So what he did was went to the store, found the smallest, yet most expensive thing and decided to throw it on a specific finger. Now, his wife is subject to his "circle" (because a ring has no beginning or end) and will not be asked out by other men, unless, of course, they are blind.
But why a ring? why not a watch? or a necklace? or a nametag. . . well, the answer here can come from the girl's standpoint. A gold or silver ring basically matches every single outfit. Diamonds form all colors when the light hits them right, so it will match with everything the girl can think of. Also, watches are more non-chalant and might not be noticed. (note: watches can either go on the left or right arm and everyone wears them on one or the other. Rings can go on 9 fingers, until it becomes subject to one) I think the Hawaiians did the smart thing though. They just picked a flower, and threw it on the left ear if she were single, or the right side if she were taken. Aloooooha!
Thus the ring becomes the socially accepted way to tell if a girl is married or single. Now men everywhere will know exactly who is married, who is not, and who is lying that they are.
