There was an old girl from Kilkenny,
Whose usual charge was a penny.
     For the half of the sum
     You might roger her bum –
A source of amusement to many.

Norman Douglas:
"Kilkenny, a slumbrous old town famed for its cats and monastic ruins, is not the kind of place to harbour people of this profession. Puzzling over the matter, and scrutinizing the text more closely, I find that the lady is described not as of Kilkenny but as from there. I conclude, accordingly, that in youth she found her way from the green fields of Leinster into some Dublin establishment, like many another country girl; and that it is her activities in the capital which are here commemorated. Be that as it may, nobody can complain of her charges."
