A farmer had five female pigs and, as times were hard,
he had determined to take them to the county fair and
sell them. While at the fair, he met another farmer
who owned five male pigs. After talking a bit, they
decided to mate the pigs and split everything 50/50.
The farmers lived sixty miles away from one another
and so they agreed to drive thirty miles and find a
field in which to mate their pigs.

The first morning, the farmer with the female pigs got
up at 5 am, loaded the pigs into the family station
wagon, which was the only vehicle they 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 grazing in
the morning, then they're pregnant, if they're in the
mud, then they're not."

The next morning they were rolling in the mud, so he
hosed them off, loaded them again into the family
station wagon and proceeded to try again.

The following morning, MUD again !!! This Continued
all week until one morning the farmer was so tired
that he couldn't get out of bed. He called to his
wife, "Honey, please look outside and tell me if the
pigs are in the mud or in the field."

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