How it works: Say two actors are given the words "blueberry pie" with which to create a scene. It might go: Actor 1: "I made a blueberry pie." Actor 2: "Yes, you made a blueberry pie. And you remember the last time we had blueberry pie?" Actor 1: "Yes, I remember. We took a picnic into the woods, and that's when you said you wanted to join a nudist colony."
