"I took a peek at "The Guidon" which they tell me is the Bible of the knobs. The more I read that little bookley, the better I like it. For example, I learned the three permissible knob answers: "Sir, Yes, Sir" and "Sir, No, Sir" and - I liked this third one best of all - "Sir, No Excuse, Sir."
-Ronald W. Reagan, 40th President of the United States
