I usually HATE these types of games. There is one that I don't mind. It does involve a bit of milling about though. Make a list that includes trivia tidbits that you know about each person. The guests have to find out which item applies to whom and get them to sign the page.
The list might include:
This person has a pet bird.
This person enjoys quilting.
...refuses to write in cursive.
...has never eaten a traditional Thanksgiving Meal.
...likes bacon for breakfast
Good conversations starters for later too
Silly is you in a natural state, and serious is something you have to do until you can get silly again.
Choose your friends by their character and your socks by their color...choosing your socks by their character makes no sense and choosing your friends by their color is unthinkable. anon
