I heard a similar story from an old stockman in New South Wales - truly 'Back-o-Bourke' more than 50 years ago that began:

Hear the tale of Nabob, son of Paybob, absolutely no fucking relation to Twobob.

He was on his way unto Jerusalem when he was set upon by bandits.
But these were not ordinary bandits, they were arse bandits,
Who ragged, bagged and shagged him and left him with his arsehole tingling and his pockets jingling.

When he came unto Jerusalem he went unto the apothecary who said "Squeeze," and he squoze and lo and behold, a dirty great yellow bubble arose.
"Thou art rotten, rotten, rotten to the core. Cast thyself away for forty days and forty nights."
So he cast himself away for forty days and forty nights, but he was not alone, there were thousands of the bastards, all rotten, rotten, rotten to the core.

This is all I remember of a 20 minute recitation. I wish I could find the rest of it.
