When I first moved to Los Angeles, I was going to the same gym as actor Barry Newman, who played Kowalski (a Vietnam War hero-turned-pill-addicted driver for hire) in the seminal film "Vanishing Point." The main thing I remember about this dude was that he would walk around the locker room, naked, yelling, "Let's go! Let's go! Let's go!" I think he had Tourette's syndrome.
