Once upon a time in Poland, a Jewish man was travelling in a train and since his trip was long, he had brought some food; fish, to eat on the way. A co-passenger was watching him eat. Then he opened his mouth and said to the Jew; "I've heard that you Jews are very smart people". The Jew answered back: "it's because we eat fish". The Polish asked: "may I buy the other fish, you have, from you". "Yes, by all means", said the Jew. After having eaten the fish with good appetite, the Polish man looked angrily at the Jew and said: "you took too much for this fish, I could have gotten it for much less in the fish market"! The Jew replied to him: "see it works already"!
