Famous quotes containing the words lines and/or overhead:

    Who will in fairest book of Nature know
    How virtue may best lodged in beauty be,
    Let him but learn of love to read in thee,
    Stella, those fair lines which true goodness show.
    There shall he find all vices’ overthrow,
    Not by rude force, but sweetest sovereignty
    Of reason,
    Sir Philip Sidney (1554–1586)

    What a fog! Plane been buzzin’ around overhead for the last half hour. Must be like trying to find your way through the inside of a cow. I never did see such a country. Even the birds are walkin’.
    Dalton Trumbo (1905–1976)
