Famous quotes containing the words table and/or universal:

    “A child who is not rigorously instructed in the matter of table manners is a child whose future is being dealt with cavalierly. A person who makes an admiral’s hat out of linen napkins is not going to be in wild social demand.”
    —Fran Lebowitz (20th century)

    “So having said, a while he stood, expecting
    Their universal shout and high applause
    To fill his ear; when contrary, he hears,
    On all sides, from innumerable tongues
    A dismal universal hiss, the sound
    Of public scorn.”
    —John Milton (1608–1674)
