Divide into groups of 4-6 people. Give everyone a sheet of paper and ask them to write the first sentence of a story at the top of the page. It may begin "Once upon a time..." if they like. Then they pass the page along to the next person in the group. That person reads the first sentence and adds one more to it to continue the story. Then that person folds the top of the page backwards so only his or her own single sentence is visible and passes the page to the next person. That person writes one more sentence, folds the paper back to hide the previous sentence, and passes it along again. When the pages have passed through the entire group one or two rounds, everyone unfolds the pages and reads the stories. They are often hilarious, and this game usually generates contagious laughter.
