Famous quotes containing the words head and/or tube:

    Therefore with idle hands and head I sit
    In late December before the fire’s daze
    Punished by crimes of which I would be quit.
    Allen Tate (1899–1979)

    One of the great natural phenomena is the way in which a tube of toothpaste suddenly empties itself when it hears that you are planning a trip, so that when you come to pack it is just a twisted shell of its former self, with not even a cubic millimeter left to be squeezed out.
    Robert Benchley (1889–1945)
