Who Am I?

On slips of paper, or 3x5 cards write the name of some famous person, or character.
Tape the name on each group member's back (make sure they don't see the name).
When everyone has a name taped on their back, instruct them to discover what name is written on their back by asking others yes or no questions about the person.
For example: Am I a real person? Am I an adult? Am I male? Was I born in the United Kingdom? By narrowing the answers down, they may discover "who they are" and if they are correct, you may choose to give them a token prize.
