I was at a party where we played "Who am I?"
The hostess secretly wrote names of famous people on small pieces of paper (it could be anyone famous - actor, singer, author, president, athlete). The paper was then taped to our backs and we walked around the party asking people questions about who we were..."Am I a man or woman?" - "Am I still alive?" - "Did I commit a crime?", etc...
You can ask only 5 questions per person, but you can talk to as many people at the party as you'd like (ie: you ask Bob 5 questions about who you are & if you don't have the answer yet, you can move onto Sue, etc....) The answers given have to be short, like "yes" or "no" , "alive" or "dead", etc....
This was a great ice breaker, especially for those guests who didn't know each other AND it makes it especially funny if the person is a "colorful" character like Mike Tyson, Little Richard, or Amy Winehouse :-)
