The designers over at Apple weren’t going to release Siri without inserting a few cute jokes. Ask her to sing you a song and she’ll respond, in her normal intonation, “Daisy, Daisy, give me your answer, do.” Ask what the meaning of life is and she might say, “I can’t answer that now, but give me some time to write a very long play in which nothing happens.”
Ask how much wood would a woodchuck chuck if a woodchuck could chuck wood – she’ll say, “It depends on whether you were talking about African or European woodchucks,” or even, “42 cords of wood, to be exact. Everyone knows that.”
