The only cow in a remote little Highland village stopped giving milk.

The people did some research and found they could buy a cow down in Perthshire for 100 pounds. They bought the cow and the cow was wonderful. It produced lots of milk all of the time and the people of the little Highland village were pleased and very happy.

They decided to acquire a bull to mate with the cow and produce more cows like it. Then they would never have to worry about their milk supply.

They bought a bull and put it in the pasture with their beloved cow.
However, whenever the bull came close to the cow, the cow would move away. No matter what approach the bull tried, the cow would move away from the bull and he could not succeed in his task. The people of the little remote Highland village were very upset and decided to ask Piper MacKay (who did a little veterinary work on the side and who was visiting his cousins in the village) what to do.

They told Piper MacKay what was happening. "Whenever the bull approaches our cow, she moves away," the village leader 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 walks away to the other side."

Piper MacKay thought about this for a minute and then asked, "Did you by chance acquire this cow from Perthshire?"

The people were dumbfounded, since they had never mentioned where they bought the cow.

"You are truly a wise vet," they said. "How did you know we got the cow in Perthshire?"

Piper MacKay shrugged, "My wife is from Perthshire."
