"So, you don't have laughs as a reference point any more, it becomes a bit of a science after that. And the last thing, you would love to be able to depend on a sense of spontaneity, but hours of waiting and then hours of repetition are not conducive to spontaneity so those are your obstacles. On the other hand it's a lot of fun. Plunging into a bit of physical comedy and abandoning all dignity, no one can really hurt you much after you much after that, once you've done it."
