Famous quotes containing the words rock and/or mantle:

    So there he is at last. Man on the moon. The poor magnificent bungler! He can’t even get to the office without undergoing the agonies of the damned, but give him a little metal, a few chemicals, some wire and twenty or thirty billion dollars and, vroom! there he is, up on a rock a quarter of a million miles up in the sky.
    Russell Baker (b. 1925)

    There are a sort of men whose visages
    Do cream and mantle like a standing pond,
    And do a willful stillness entertain,
    With purpose to be dressed in an opinion
    Of wisdom, gravity, profound conceit,
    As who should say, “I am Sir Oracle,
    And when I ope my lips let no dog bark!”
    William Shakespeare (1564–1616)
