Improv is a very good hobby to have. It helps you to get out of difficult situations.<p>One of the things done at an improv show is called "story in 4".<p>To do a four-person improv story with random changes, have one player start a scene. Ring a bell or shout "Change!" at random times. When that happens, the last speaker must change their last line, or a new person must jump in to shift the plot, setting, or character traits completely.<p>It is super fun on stage and very useful in meeting rooms where you might need to pivot quickly.
