I know that I can sing really loud. It's like having that really big Evinrude engine on the back of your fishing boat. But I've been trying to be more dynamic with my voice, and not just singing on 10 all of the time out of terror.
People expect us to be different, but we're not. We're very similar people, and it's because we're so similar and close to each other that we make each other laugh - in fact we make each other laugh more than we make anyone else laugh.
