Have everyone sit in a circle with you in the center. You can either sit in chairs, or have place markers (bookbags, etc) behind each person.
Name off something you have, have done, or can do (ie ÛÏCross if you have ever jumped out of a plane, if you own a dog, have blue eyes).
Those people that can give a positive answer to the question will cross the circle and find an open seat of someone else that answered positively.
Since you have one less chair then there are people in the group, and you found an opening quickly, there should be one person left in the center. This person then gets to pick the next topic.
