Your Favorite Unique Wedding Favors?

Whenever we go to weddings I'm always curious to see if they have unique wedding favors, or if they have favors at all. Indeed, we live in an area where wedding favors are not common but we have family and friends in areas where they are expected so we've seen both. Whenever I see wedding favors I'm always curious as to what I would have chosen if we would have had favors at our wedding (since we planned our wedding in a week wedding favors weren't on our top ten list of things to get done). What is the best wedding favor you've seen? We'd love to hear about it!
