This game calls for as much silence as possible. Each person decides on a number from 1 to 3. While not saying a word, everyone in the group wanders around shaking hands with others. The number of shakes should match the number chosen. There will be a moment of tension when numbers don't match up. People should silently decide how to group themselves. Eventually everyone will be in 3 groups. Often the groups are evenly divided - it must be psychic.
