I'm not sure I'd want to walk around wearing a giant, gold, diamond-encrusted hamburger on my finger . . . but you might.  Hey, to each her own.

McDonald's just had a jewelry designer make a Big Mac RING.  It's made from 18-karat gold . . . it's got a bunch of diamonds, sapphires, and other jewels . . . and it's worth approximately $12,500. 

And if you want it, all you have to do is tweet about your love of the Big Mac using the hashtag #BlingMacContest before Valentine's Day. 

Then they'll pick the best tweet and give that person the ring. Congratulations?
