I'm grew up a huge fan of The Three Stooges and Monty Python, so somebody getting slapped in the face with a fish, or falling out of a chair, or running into a door, or tripping over their own feet and eating it, is all stuff I find really, really funny.
I was in the emergency room twice with heart palpitations and panic attacks. As one of my actor friends pointed out: your body doesn't know that you're making art. You think about struggle and challenge and you imagine yourself weighing 302 pounds and being restricted and in despair. Your body doesn't know that that's not the case.
