When I lived in Leeds in the 70's, a one-armed blacksmith at the Adelphi Folk Club used to recite monologues, with much waving of arm and empty sleeve, including one called the Building of the Pyramids. In this version of the story, the workers toiling on the pyramids were Irish. Moses, after several unsuccessful plagues, finally got it right when he put 'a blight on the Gyp Guiness,' and they had to let his people go.
I remember only one piece of it:

'Now Moses was driving a dumper,
At the site of Pharoah's new tomb.
He said: They should have cremated the bugger -
It wouldn't half have saved 'em some room!'

Anyone remember the rest?
