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 and the farmers were worn out.
The next morning, one was too tired to even get out of bed. So he called out 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."
