I'm helping a friend plan his New Years Eve party. It will be at his house, and we're inviting pretty much everyone we know. Age range is probably 19-28. We've got plenty of beverages (alcoholic and non) and food, but we need ideas for games and activities. We want the party to be more than just eating/drinking/socializing. Please share your party stories and ideas. We want a party people will be talking about for a while.
