So maybe you're not too into Vegas and Atlantic City for wagering. That doesn't mean you can't bring some friendly bets to your relationship.

Instead of betting real money on the big game, bet love coupons, say for cleaning the house, a foot rub, or running errands. You'd be amazed how much you'll root for the home team when it means no laundry for a week.

Little things like this can spice up any relationship. So mix in the wagering, plop down on the sofa for the big game, and see who has to run the dishwasher tomorrow.
