Everyone sits in a big circle, post-its and writing utensils are handed out to all. Each person is told to write the name of a famous person (pretty much anyone that everyone in the circle knows) on the post-it and then put it in a hat. The post-its are then redistributed at random. Each kid must then take turns asking yes or no questions about their new identity. They may ask as many as they need to until they figure it out.
