A few changes to Bryn Pugh's version

There was an old woman of 92, parlez-vous (tris)
She dropped a fart and away it flew,
Inky pinky parlez-vous.

The fart went rolling down the hill, parlez-vous (bis)
Knocked a copper off his feet,
Inky pinky parlez-vous.

The copper pulled out his rusty pistol, parlez-vous (tris)
Shot it over in to Bristol,
Inky pinky parlez-vous.

The Mayor of Bristol wasn't at home, parlez-vous (tris)
So the fart went on to Rome,
Inky pinky parlez-vous.

The Emperor of Rome was having his din, parlez-vous (tris)
Opened his gob and the fart flew in,
Inky stinky parlez-vous.

The fart went rolling round his belly, parlez-vous (tris)
Formed into a slice of jelly,
Inky pinky parlez-vous.

The fart of jelly came out his bum, parlez-vous (tris)
So the fart went on to Brum,
Inky pinky parlez-vous.

The Brummies couldn't stand the smell, parlez-vous (tris)
So they kicked it into hell,
Inky pinky parlez-vous.

The Devil he poked the old woman in the tits, parlez-vous (tris)
He said you dirty little shit,
Inky pinky parlez-vous.

Can't think of any more :-)
