A Polish man was walking down the street, in Cork, carrying a brown paper bag. He ran into one of his friends, Fergus McCarthy, who asked, "Hey! What do you have in the bag?"
The Pole tells Ferg that he has some fish in the bag. His friend says, "Well, I'll make you a bet. If I can guess how many fish you have in the bag, you'll have to give me one."
The man says, "I'll tell you what. If you tell me how many fish I have in this bag, I'll give you both of them."
