the second rule of improvisation is... YES, AND

The second rule of improvisation is not only to say yes, but YES, AND. You are supposed to agree and then add something of your own. If I start a scene with “I can’t believe it’s so hot in here,” and you just say, “Yeah…” we’re kind of at a standstill. But f I say, “I can’t believe it’s so hot in here,” and you say, “What did you expect? We’re in hell.” Or if I say, “I can’t believe it’s so hot in here,” and you say, “Yes, this can’t be good for the wax figures.” Or if I say, “I can’t believe it’s so hot in here,” and you say, “I told you we shouldn’t have crawled into this dog’s mouth,” now we’re getting somewhere. 

To me YES, AND means don’t be afraid to contribute. It’s your responsibility to contribute. Always make sure you’re adding something to the discussion. Your initiations are worthwhile.

The next rule is MAKE STATEMENTS. This is a positive way of saying “Don’t ask questions all the time.” If we’re in a scene and I say, “Who are you? Where are we? What are we doing here? What’s in that box?” I’m putting pressure on you to come up with all the answers.

In other words: Whatever the problem, be part of the solution. Don’t just sit around raising questions and pointing out obstacles.
