I think that when you get dressed in the morning, sometimes you're really making a decision about your behavior for the day. Like if you put on flipflops, you're saying: 'Hope I don't get chased today.' 'Be nice to people in sneakers.' ↗
I like to use 'I Can't Believe it's Not Butter' on my toast in the morning, because sometimes when I eat breakfast, I like to be incredulous. How was breakfast? Unbelievable. ↗
I'm very silly as a person, but quality silliness on-screen has more of an art to it. Harrison Ford, whom I was in 'Morning Glory' with, has mastered that dry funny better than anyone. ↗
