The Dumb Pig Farmer

There was this pig famer and he was a bit dumb, and he
wanted to get his pigs breeding.  Trouble was they were
all sows.

He calls the vet and the vet tells him to use artificial
insemenation.

Well he isn't too sure about this but he doesn't want to
appear too stupid, so he figures it out for himself that
it means he should shag the pigs himself to get them
pregnant.

The next day he piles them all up in the back of his truck
and takes them into the bush and roots every one of them.
He comes home exhausted and gets into bed.  The next morning
he gets up and calls the vet to see how he can tell if the
pigs are pregnant.

The vet says that they will all be rolling around on their
backs if they are pregnant.

So the pig farmer looks out into the field and nope, they're
all standing around eating.  "Buggar!" says the pig farmer.
So he packs them all into the back of his truck and takes them
back out into the bush and shags every one of them all again.

He again returns home exhausted and goes straight to bed.
When he awakens, he looks out into his field and they are all
still standing around.  So again, he loads them all into his
truck and takes them off into the bush and roots them all a
third time. 

The next morning he is absolutely exhausted.  He lies there,
and says to his wife, "I'm exhausted, can you look out and tell
me what the pigs are doing?".

So she looks out the window and exclaims "My goodness, this is
the strangest thing I've ever seen.  The pigs are all in the
truck and theres one in the cab beeping the horn!"
