Famous quotes containing the words flash and/or lock:

    I think that in the swift white mind’s brain
    Neurons flash images of a world
    Undead and deathless, burgeoning again.
    I think that Spring will come this way, unfurled.
    Allen Tate (1899–1979)

    There warn’t anybody at the church, except maybe a hog or two, for there warn’t any lock on the door, and hogs likes a puncheon floor in summertime because it’s cool. If you notice, most folks don’t go to church only when they’ve got to; but a hog is different.
    Mark Twain [Samuel Langhorne Clemens] (1835–1910)
