Famous quotes containing the words joint and/or shoulder:

    No Government can be long secure without a formidable Opposition. It reduces their supporters to that tractable number which can be managed by the joint influences of fruition and hope. It offers vengeance to the discontented, and distinction to the ambitious; and employs the energies of aspiring spirits, who otherwise may prove traitors in a division or assassins in a debate.
    Benjamin Disraeli (1804–1881)

    America I’m putting my queer shoulder to the wheel.
    Allen Ginsberg (b. 1926)
