Are there any Moldavians in this evening? No? Alright!! This Moldavian goes to visit another village* and wants to buy a pig. He asks the first man he comes across how much his pig costs. The villager holds out all the fingers of his hands, so he counts out 10 golden beans from his pocket. The villager then slaps him around the face and goes off cursing. Perplexed, our man then asks the next villager he comes across, is again shown two splayed hands, and is once again hit around the face when he proffers 10 golden beans. This happens the requisite 3 times until he meets a man who accepts his payment gratefully and hands over a pig. Our hero inquires as to why the other villagers were so angry. “My friend”, says his trading partner, “nobody in this village has 10 fingers; I myself was born with 8. Good luck with the pig.”
* In reality this would never happen. But for the purposes of this joke we're going to imagine that he’s noticed the signs of inbreeding in his pigs, and so is looking to sire his gilts from other bloodstock; he’s thinking of trying to use a goat, but failing that another pig would probably do.
