Divide into 2-4 groups. Give each group time to come up with as many Christmas carols as they can. After time is called, each group takes turns singing part of a Christmas carol on their list. If any other group has the same carol on their list, no points are given. If no other group has the carol on their list, they get 100 points. Keep it fast paced. Groups should mark off carols already sung. Group with the most points at the end wins.
