Has anyone posted this 'un?

    My sweetheart's a mule in the mines;
    I drive her without any lines.
    On the bumper I sit,
    I chew and I spit
    All over my sweetheart's behind.

Or this one that I learned from John Greenway in Boulder, Colorado, 1959:

    Pa didn't raise no corn this year,
    Pa didn't raise no termaters.
    He had bad luck with the cabbage crop,
    But, oh, my God, them 'taters!

          Sixty cent pertaters!
          Right nigh six-bit pertaters!
          He had bad luck with the cabbage crop,
          But, oh, my God, them 'taters!

And Jeannie Robertson sang this one for me (Aberdeen, Scotland, 1958):

    Maggie, Maggie,
    Come and kiss your Sandy.
    Come awa' and spoon wi' me
    In beneath this bramble tree.
    Oh, Maggie, Maggie,
    Ye set my heart on fire.
    If it wasnae for my wife
    I'd mak' ye Mrs. McIntyre!

And, finally, from Mike Meyers, in England, 1957:

    Oh the black cat piddled in the white cat's eye,
    The white cat said "Cor Blimey!"
    The black cat said, "You silly sod,
    You shouldn't stand behind me!"

Enuff, already!
