A new Entered Apprentice was asked by the lodge instructor: "What is Masonry?"
The EA dutifully replied: "A system of morals veiled in allegories and illustrated by symbols."
The lodge instructor said, "So it is written, yet I admonish you to be like the greatest of thieves."
The EA was puzzled: "What do you mean?"
The lodge instructor replied: "When a great thief enters a royal palace, he does not settle for the jewels left out in plain sight."
