Famous quotes containing the word fish:

    Let a man get up and say, “Behold, this is the truth,” and instantly I perceive a sandy cat filching a piece of fish in the background. Look, you have forgotten the cat, I say.
    Virginia Woolf (1882–1941)

    When the weather is bad as it was yesterday, everybody, almost everybody, feels cross and gloomy. Our thin linen tents—about like a fish seine, the deep mud, the irregular mails, the never to-be-seen paymasters, and “the rest of mankind,” are growled about in “old-soldier” style. But a fine day like today has turned out brightens and cheers us all. We people in camp are merely big children, wayward and changeable.
    Rutherford Birchard Hayes (1822–1893)

    The progress
    Is permanent like the preordained bulk
    Of the First National Bank
    Like fish sauce, but agreeable.
    John Ashbery (b. 1927)
