> As the farmers lived 60 miles from each other, they agreed to meet
> half-way 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, and drove the 30 miles.
>
> While the pigs were mating he asked the other farmer, "How will I know;
> if they're pregnant?"
>
> The other farmer replied, "Tomorrow morning, if they're in the grass
> grazing, then they're pregnant. If they're in the mud, then they're not."
>
> The next morning they were rolling in the mud, so the farmer called the
> other farmer, hosed his pigs off; loaded them into the family station
> wagon and drove off to try again.
>
> The following morning, it was mud again !!
>
> This continued for a week until one morning the farmer was so tired he
> couldn't get out of bed.
>
> He called out to his wife, "Honey, please look outside and tell me if the
> pigs are in the mud or in the field."
>
> "Well, neither," yelled his wife. "They're all in the station wagon, and
> one of them's honking the horn."
