Are pigs smart?

A farmer had five female pigs. Times were hard, so he decided to take themto the county fair and sell them.

At the fair, he met another farmer who owned five male pigs. After talking abit, they decided to mate the pigs and split everything 50/50. The farmerslived sixty miles apart. So they agreed to drive thirty miles each, andfind a field in which to let the pigs mate. The first morning, the farmerwith the female pigs got up at 5 A.M., loaded the pigs into the familystation wagon, which was the only vehicle he had, and drove the thirtymiles. While the pigs were mating, he asked the other farmer, "How will I know ifthey are pregnant?"

The other farmer replied, "If they're lying in the grass in the morning,they're pregnant . If they're in the mud,they're not."

The next morning the pigs were rolling in the mud. So he hosed them off,loaded them into the family station wagon again and proceeded to try again.This continued each morning for more than a week.

The next morning he was too tired to get out of bed. He called to his wife,"Honey, please look outside and tell me whether the pigs are in the mud orin the grass."

"Neither," yelled his wife, "they're in the station wagon and one of them is honking the horn."
