It's horrible for someone to listen to someone learning any instrument - when I was first learning the banjo, I used to have to go out and sit in the car, and even in the summertime I'd have to roll up the windows. Because you just couldn't practice a banjo or a fiddle with other people around. Unless they're being paid.
Steve MartinYour only guidepost is your own instinct and judicious editing. In my stand-up act I learned that in the first 10 minutes I could say anything and it would get a laugh. Then I'd better deliver. In the movie it's the same thing. You get a lot of laughs when people first sit down and then the story better kick in. Many years in front of an audience, I would hope, give me a sense of what works.
