I learnt this one at school in the 60s - some verses might be missing.. . . .

The moon shone on the village green
It shone on little Nell
Was she fetching water?
Was she fuckin hell

She was waiting for her lover
The dirty cross-eyed bugger
Who wasn't fit to shovel shit
From one hole to another

The babe was born on Christmas morn
With eyes as black as charcoal
A slimy dick, ten inches thick
And a double barreled arsehole!
