One day a farmer goes into town to see a vet to see if how to tell that his pigs are pregnant. The vet says that if there standing up in the morning there not pregnant, but if there rolling in the mud they are.

So the farmer goes home and loads all of his pigs in the back of his pick-up and takes them all out in the woods and fucks them all once. Then he takes them home and unloads them in there pin. Afterwards he gets tired so goes to bed.

The next morning he gets up and checks on the pigs and there standing up, so he takes them all out in the woods and fucks them all twice. Then goes home, quickly unloads them in there pin, and goes right to bed.

The next morning, very tired, the farmer gets up to check on his pigs, but they are still standing. Again, he loads them in the truck, takes them to the woods, and fucks them three times. Then he takes them home, unloads them, and goes straight to bed.

The next morning the farmer is so tired he can't even get out of bed, so he yells to his wife to come into his bedroom. He tells her to look out the window and tell him if the pigs are standing up or rolling in the mud. His wife replies neither, they're all in the back of the truck, and ones laying on the horn.
