 Authors, poets, lyricists and the like, on the other hand, have often found ambiguity to be an extremely powerful tool. Thomas Pynchon’s sentence “we have forests full of game and hundreds of beaters who drive the animals toward the hunters such as myself who are waiting to shoot them,” (Against the Day, p. 46) utilizes the referential ambiguity of ‘them’ to great effect when said by his fictionalized Archduke Ferdinand. Shakespeare’s “Ask for me tomorrow and you shall find me a grave man” (Romeo and Juliet, Act III, Scene 1 line 97–98) plays cleverly on the double meaning of ‘grave’. Comedians have often found ambiguity useful in the misdirection essential to some forms of comedy. Groucho Marx’s “I shot an elephant in my pajamas” is a classic example.
