I would have to say my ring finger. Everyone knows that the thumb is the most important finger, so there is no way I would sacrifice that one. I am constantly using my index finger to grip and point to things. My middle finger, well, my hand just wouldn't look right without it. Plus, I do use it occasionally if you know what I mean. My little finger...well, I love my little finger. Plus, a lot of different hand gestures require this finger. So I would chose my ring finger. I guess I couldn't get married, but I could still fall in love. You don't need documents to tie two people together if they really love each other.
