The only cow in a small town in Poland stopped giving milk. The people did some research and found that they could buy a cow from Moscow for two thousand roubles or one from Minsk for one thousand roubles. Being frugal, they bought the cow from Minsk. The cow was wonderful. It produced lots of milk, and the people were so happy that they decided to acquire a bull to mate with the cow and so produce more cows like it. Then they would never have to worry about their milk supply again. So they bought a bull and put it in the pasture with their beloved cow. But whenever the bull came close to the cow, the cow would move away. No matter what approach the bull tried, the cow didn't want to know. The people were very upset and decided to ask their wise rabbi for his advice. They told the rabbi what had been happening. "Whenever the bull approaches our cow, she moves away," they said. "If he approaches from the back, she moves forward. When he approaches her from the front, she backs off. An approach from the side and she just walks away to the other side." The rabbi thought about the problem for a minute and then asked: "Did you buy this cow from Minsk?" The people were amazed, because they had never mentioned where they had bought the cow. "You are truly a wise rabbi," they said. "How did you know we got the cow from Minsk?" The rabbi replied sadly: "My wife is from Minsk." A Jewish guy was up a ladder cleaning a window when a coin fell out of his pocket. He climbed down to get it and it hit him on the head.
