  • When I was young and had no sense

    In far-off Mandalay

    I lost my heart to a Burmese girl

    As lovely as the day.

    Her skin was gold, her hair was jet,

    Her teeth were ivory;

    I said, "for twenty silver pieces,

    Maiden, sleep with me".

    She looked at me, so pure, so sad,

    The loveliest thing alive,

    And in her lisping, virgin voice,

    Stood out for twenty-five.
