Famous quotes containing the words working and/or fluid:

    Every country we conquer feeds us. And these are just a few of the good things we’ll have when this war is over.... Slaves working for us everywhere while we sit back with a fork in our hands and a whip on our knees.
    Curtis Siodmak (1902–1988)

    On and on eternally
    Shall your altered fluid run,
    Bud and bloom and go to seed;
    But your singing days are done;
    Edna St. Vincent Millay (1892–1950)
