I am a salesman.

Willy was a salesman. And for a salesman, there is no rock bottom to the life. He don't put a bolt to a nut, he don't tell you the law or give you medicine. He's a man way out there in the blue, riding on a smile and a shoeshine. And when they start not smiling back--that's an earthquake. And then you get yourself a couple of spots on your hat and your finished. Nobady dast blame this man. A salesman is got to dream, boy. It comes with the territory.
