The only cow in a small Kentucky town stopped giving milk. The peopledid some research and found that they could buy a cow just across the stateline in Illinois for $200.
They brought the cow from Illinois and the cow was wonderful. Itproduced lots of milk all of the time, and the people were very happy. They decided to acquire a bull to mate with the cow to produce morecows like it. They would never have to worry about their milk supply again.They bought the bull and put it in the pasture with their beloved cow.However, whenever the bull tried to mount the cow, the cow would move away. No matter what approach the bull tried, the cow would move awayfrom the bull and he could not succeed in his quest. The people were veryupset and decided to ask the Vet, who was very wise, what to do.
They told the Vet what was happening. "Whenever the bull tries to mountour cow, she moves away. If he approaches from the back, she moves forward. When he approaches her from the front, she backs off. Anattempt from the side, she walks away to the other side."
The Vet thought about this for a minute and asked, "Did you by chance,buy this cow in Illinois?"
The people were dumbfounded, since no one had ever mentioned where theybought the cow. "You are truly a wise Vet," they said. "How did youknow we got the cow in Illinois?"
The Vet replied with a distant look in his eye, "My wife is from Illinois."
