Remember that episode that started with Hank Hill and John Redcorn in a diner, and just as John Redcorn had put a sandwich to his mouth, Hank started this really lame propane sales pitch that went something like this.
"Say John, I can tell you about another kind of sandwich. a PROPANE sandwich."
Or something to that effect. What was the title of that episode? What exactly was the context of that situation? Did Hank invite John to lunch? Did John invite Hank? Or did they just meet by chance. Did John Redcorn know that Hank was going to talk about propane with him?
