First divide into two groups, men vs. women. Then, pick group names just to add to the fun. You will need at least one judge who is not playing (you can also have more than one judge, but make sure it's an odd number). One person from the first group will pull a card, and both groups have to pick a song based on that same card and perform. The judge will decide the winner from that round (based on song selection and overall performance). Keep going until both groups have battled at least 3 times, and then declare a winner!
