Famous quotes containing the words signs and, signs and/or symptoms:

    Time has an undertaking establishment on every block and drives his coffin nails faster than the steam riveters rivet or the stenographers type or the tickers tick out fours and eights and dollar signs and ciphers.
    John Dos Passos (1896–1970)

    Mister death who signs papers
    then eats
    telegraphs simply: Shoot them
    then eats
    Denise Levertov (b. 1923)

    M.F.K. Fisher (1908–1992)
