The city couple had gone into pig farming, and bought several sows.  It was very important that the new pig farmer got his litters of piglets as soon as possible, and he found that the nearest boar was 30 miles away.  As soon as the sows came into season, the new farmer got up at 5 a.m., loaded the pigs into the family station wagon, which was the only vehicle he had, and drove the thirty miles.

While the pigs were mating, he asked the other farmer, "How will I know if
they are pregnant?" The other farmer replied, "If they're 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.

One morning the farmer was so tired, he couldn't get out of bed. He called
to his wife, "Honey, please look outside and tell me whether the pigs are
in the mud or in the grass."

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

:D :D :D Knew pigs were intelligent
