Slips of paper
Popular song lyrics To Play
On long slips of paper, write out a line or two from a popular song. It might be a recent hit (like I kissed a girl and I liked it) or something related to New Years (like Should old acquaintance be forgot And auld lang syne?).
Cut the slip of paper in half, so part of the lyric is on one half and part of the lyric is on the other half.
Hand out slips of paper to each guest as they arrive, and at some point in the evening, announce that each person has to find the other guest with the rest of their song. The first three couples to find each other win a prize.
