Famous quotes containing the word weight:

    Now mark me how I will undo myself.
    I give this heavy weight from off my head,
    And this unwieldy sceptre from my hand,
    The pride of kingly sway from out my heart.
    With mine own tears I wash away my balm,
    With mine own hands I give away my crown.
    William Shakespeare (1564–1616)
