Have two people sit in two chairs in front of the group. They will start acting out any clean, unoffensive scenario, like maybe driving a car or eating popcorn and watching a movie. Since this is not charades, they can talk. The conversations can be pretty hilarious. Then someone, anyone from the group yells "Freeze!" and both people freeze right where they are. The person who yelled "Freeze!" goes up and tags one of the two people on the shoulder. That person has to sit down and the new person takes their place, and starts acting out some other scenario without telling the other person what it is. They have to try and go along with it! Be careful though because this can quickly evolve into a WWF Smackdown! The game continues pretty much until you get tired of it. New people keep yelling "Freeze!" and tagging one of the two people and taking their place. It's really fun to see the creativity that kids come up with...
