So it seems that the Christian Philosopher John Scotus Eriugena (John the Irishman) was after havin' a bit of drink with Emperor Charles the Bald one day….
When up says the Emperor if you please:
"Tell me John, What separates the Irishman from a fool?"
…and don't you know John Scotus says to the emperor bold as you please:
"Only the table Charles me boy, only the table."
