- On building a pot of coffee: "Most people just don't know how to make good coffee. In the first place, they boil the water before they put the coffee in. Any fool knows you gotta put the coffee in the cold water and bring them both to a boil together. That way you get all of the flavor. Worst thing they do, they throw away the old grounds after using them once. What they don't know is that they are throwing away the best part. You got to keep them old grounds and you add a little fresh coffee every morning and let her boil. Shoot, you don't make a cup, you build a pot. You don't really get a good pot until you've been usin' it about a week. Then it's coffee!" On observing a prisoner Matt is releasing from jail, Chester addresses the prisoner, "You look like the dogs had you under the house." On a long ride with Matt, Chester declares, "Why I'm so hungry, my stomach is growing teeth."
