I remember it as:
Where's the Princess asks Daniel?
She's upstairs in bed with Arthritis, replies the King.
Hah! Says Daniel, I know the Ritis family well and
Arthur is the dirtiest bastard of them all.


Also the opening I remember as
It was the night of the kings feast and the knights were seated
at the four corners of the round table flinging sheep-shit at
each other, as in those days bull-shitting had not been invented.

Mind you, these memories are from some 50 years ago, so.......
