What is express mirth?

Famous quotes containing the words mirth and/or express:

    I saw my lady weep,
    And Sorrow proud to be advanced so
    In those fair eyes where all perfections keep.
    Her face was full of woe;

    But such a woe, believe me, as wins more hearts
    Than Mirth can do with her enticing parts.
    —Unknown. I Saw My Lady Weep (l. 1–6)

    When I quote others I do so in order to express my own ideas more clearly.
    Michel de Montaigne (1533–1592)
