Famous quotes containing the words universal and/or joint:

    The universal regard for money is the one hopeful fact in our civilisation. Money is the most important thing in the world. It represents health, strength, honour, generosity and beauty.... Not the least of its virtues is that it destroys base people as certainly as it fortifies and dignifies noble people.
    George Bernard Shaw (1856–1950)

    What’s a joint of mutton or two in a whole Lent?
    William Shakespeare (1564–1616)
