I used to have weird practices in crowded used-book stores in New York where I'd go in and just stomp my foot and see what fell from the shelf. And of course, because it's an unexpected encounter, there's always some magic that comes from it.
I think dancing is contributed hugely to how I am as an actor, just a level of comfort in my body and in movement. Things can become strangely physically technical when you're acting, and often something that just feels so unnatural is actually what you need to do in a certain scene.
