Famous quotes containing the words open, game and/or license:

    Rats!
    They fought the dogs and killed the cats,
    And bit the babies in the cradles,
    And ate the cheeses out of the vats,
    And licked the soup from the cooks’ own ladles,
    Split open the kegs of salted sprats,
    Made nests inside men’s Sunday hats,
    And even spoiled the women’s chats
    By drowning their speaking
    With shrieking and squeaking
    In fifty different sharps and flats.
    Robert Browning (1812–1889)

    Vanessa wanted to be a ballerina. Dad had such hopes for her.... Corin was the academically brilliant one, and a fencer of Olympic standard. Everything was expected of them, and they fulfilled all expectations. But I was the one of whom nothing was expected. I remember a game the three of us played. Vanessa was the President of the United States, Corin was the British Prime Minister—and I was the royal dog.
    Lynn Redgrave (b. 1943)

    All is possible,
    Who so list believe;
    Trust therefore first, and after preve,
    As men wed ladies by license and leave,
    All is possible.
    Sir Thomas Wyatt (1503?–1542)
