Crystal Hawks

Here are the "rules" that Crystal and Brisco quote back and forth to each other:
  1. "You call me Miss Hawks"
  2. "Your life story is your own business"
  3. "You ain't hearing my life story either."
  4. "Try chains. They work a lot better than ropes."
  5. "Never underestimate a man's love for his horse."
  6. "The biggest gun usually wins."
... and then there's "Rule Number Whatever": "Never judge a book by its cover."
