You know that thing that Jerry Seinfeld does where his voice suddenly gets very loud and high? He may have picked up that trick about invading your earspace when he briefly dabbled in Scientology 30 years ago: "You would just understand that there's this kind of voice, and then there's this kind of voice, and then there's this kind of voice. I wasn't a natural performer at all, so I learned. I was always a pretty good writer in the beginning, but I really had to learn how to perform. Just a little thing like that, understanding that really helped me on stage to understand how you have to invade the space of the audience a little bit." [Parade]
