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

    Thank God we’re living in a country where the sky’s the limit, the stores are open late and you can shop in bed thanks to television.
    Joan Rivers (b. 1935)

    I have a notion that gamblers are as happy as most people, being always excited; women, wine, fame, the table, even ambition, sate now & then, but every turn of the card & cast of the dice keeps the gambler alive—besides one can game ten times longer than one can do any thing else.
    George Gordon Noel Byron (1788–1824)

    Only one marriage I regret. I remember after I got that marriage license I went across from the license bureau to a bar for a drink. The bartender said, “What will you have, sir?” And I said, “A glass of hemlock.”
    Ernest Hemingway (1899–1961)
