Mainly, I thought of Barney as a kid. You can always look into the faces of kids and see what they're thinking, if they're happy or sad. That's what I tried to do with Barney.
We began to do little things, have little scenes where we just talked about things that had nothing to do with the plot. In fact, in the beginning, they didn't want us to do that. But as time went on, you see that in so many shows. I think we were the first to do that.
