A historical one based on the popular mid-19 century popular song, 'I Dreamt that I Dwelt in Marble Halls' (from my mother's youth - seen in a ladies lavatory in New Brighton)

I dreamed I was tickling my old feller's feet
With a glass of sweet oil and a feather.
The more that I tickled, the louder he laughed
Till the cheeks of his arse flapped together
Jim Carroll
