All performers line up on stage and are given a topic by the audience. One of them will step forward and talk about the topic (even if they don't know about it and are making it up). At any point, another performer can shout "Challenge!" and challenge one or all of the "facts" just stated. A host will then decide who is "right," and that person will continue until he or she is challenged by someone else.
A Thanksgiving-themed game. An audience member is grilled about members of his or her family that would usually be present at a family dinner. The performers then perform a scene using that person's family.
This is a game that involves any and every improv game there is. Starting with any given game, a scene is performed. At any time, a performer can yell "Freeze!" and change the game. And it continues to change until we don't feel like changing it anymore. It's CRAZY IMPROV!!
