Famous quotes containing the word square:

    I walked by the Union Square Bar, I was gonna go in. And I saw myself, my reflection in the window. And I thought, “I wonder who that bum is.” And then I saw it was me. Now look at me, I’m a bum. Look at me. Look at you. You’re a bum.
    —J.P. (James Pinckney)

    Rationalists, wearing square hats,
    Think, in square rooms,
    Looking at the floor,
    Looking at the ceiling.
    They confine themselves
    To right-angled triangles.
    Wallace Stevens (1879–1955)

    The square dance fiddler’s first concern is to carry a tune, but he must carry it loud enough to be heard over the noise of stamping feet, the cries of the “caller,” and the shouts of the dancers. When he fiddles, he “fiddles all over”; feet, hands, knees, head, and eyes are all busy.
