robomatic and harpgirl,   Sorry about the pun.  I unusually don't poke fun...even in jest. 

Here is another example of this 'song' from a MS from 1905-07.   There are songs, stories, toasts and other doggerel poems in this collection (See here).  None of the songs in this collection have tunes indicated.

-: GO CHILD AND KISS YOUR PA :-

She lay start naked on the bed,
So round so fair and chubby,
And I beside her naked too,
With each hand held a bubby,
I kissed her lips with merry glee,
And 'neath her chin did chuck her,
And then our legs were intertwined,
And I began to FUCK her,
Pull out she cried dont spend inside,
Or I'll get into trouble,
I did and on her snowy breast the stream did squirt and
bubble I gazed into her frightened eyes,
And into laughter burst, and said my Dear that's the Youngest child I guess you ever nursed,
She scooped it up with one fair hand
And laughing a soft Ha? Ha?
She threw it in my face and cried
Go child
and kiss
your PA!


Notes: This is from a 1905-07 manuscript from New York state near Albany.  No tune is indicated.
