IMHO this is one of the funniest text in the history of insults.
Letter of the Zaporozhian Cossacks of Ukraine replying to the Sultan of Turkey:
O sultan, Turkish devil and damned devil’s kith and kin, secretary to Lucifer himself. What the devil kind of knight are thou, that canst not slay a hedgehog with your naked arse? The devil shits, and your army eats. Thou shalt not, thou son of a whore, make subjects of Christian sons; we have no fear of your army, by land and by sea we will battle with thee, f##k thy mother.
Thou Babylonian scullion, Macedonian wheelwright, brewer of Jerusalem, goat-fu##er of Alexandria, swineherd of Greater and Lesser Egypt, pig of Armenia, Podolian thief, catamite of Tartary, hangman of Kamyanets, and fool of all the world and underworld, an idiot before God, grandson of the Serpent, and the crick in our dick. Pig’s snout, mare’s arse, slaughterhouse cur, unchristened brow, screw thine own mother!
So the Zaporozhians declare, you lowlife. You won’t even be herding pigs for the Christians. Now we’ll conclude, for we don’t know the date and don’t own a calendar; the moon’s in the sky, the year with the Lord, the day’s the same over here as it is over there; for this kiss our arse!
