  • His father would beg, his mother implore,
    'Godfrey Gordon Gustavus Gore,
    We really do wish you would shut the door!'

    Their hands they wrung, their hair they tore;
    But Godfrey Gordon Gustavus Gore
    Was deaf as the buoy out at the Nore.

    - William Brighty Rands, 'Godfrey Gordon Gustavus Gore'.
