Select four or five people from the group to be "psychiatrist" and them send them out of the room. the remaining members of the group chooses a 'problem' that needs to be solved. For example-each person assumes the characteristics of the person to his or her right. For example, if asked the color of the "patients" hair, the person questioned would say blonde if that is the hair color of the person on his right. Other 'problems' could be all are person on left, all are one person in the group, every other person, etc...
