Improv rules

Long ago and far away my sister-in-law was involved with an improvisational theater group at Yale. She once shared with me a type-written (yes: type-written, not computer drafted) page of “rules” for doing improv theater. I remember liking them a lot, and thinking that they had applicability in lots of other settings. Last week when the thread got started about games, I started looking for that tattered sheet of paper but couldn’t find it. I finally searched online for the improv group she’d been a part of at Yale, The Purple Crayon, and wrote to them to inquire. They wrote back with the link to the list, which now lives online. Hurray!
