Famous quotes containing the word malignant:

    How did you get in the Navy? How did you get on our side? Ah, you ignorant, arrogant, ambitious—keeping sixty two men in prison cause you got a palm tree for the work they did. I don’t know which I hate worse, you or that malignant growth that stands outside your door. How did you ever get command of a ship? I realize in wartime they have to scrape the bottom of the barrel. But where’d they ever scrape you up?
    Frank S. Nugent (1908–1965)
