  • Lady, lady, should you meet

    One whose ways are all discreet,

    One who murmurs that his wife

    Is the lodestar of his life,

    One who keeps assuring you

    That he never was untrue,

    Never loved another one...

    Lady, lady better run.

  • As compasses tell us direction

    So Donald consults his erection,

    And where it is pointed

    A new love’s anointed.

    His lodestar is lust, not affection.
