There are bits at the table read that destroy, so much so that we can't wait to do it in taping. And then, no reaction. And then there are times when I can't get the right read on a line in rehearsal, and then the audience howls at it. The strange thing is I still don't know why it happens like that. It's not like afterwards I think, 'Now I know why that worked!'
