    “A fool, A fool! I met a fool i’ the forest,
    A motley fool. A miserable world!
    As I do live by food, I met a fool,
    Who laid him down and basked him in the sun,
    And railed on Lady Fortune in good terms,
    In good set terms, and yet a motley fool.”
    —William Shakespeare (1564–1616)
