Pigs
Ivor Brown was tired of the rat race of New York City. He decided to move to the peace and quiet of the country. He bought a small farm and moved away from the big city.
Not knowing what to do with the farm, he talked to his neighbours. They suggested going to the local auction and buying some live stock. Ivor did just that. In fact, he got a good deal on a dozen pigs at the auction.
When he got them home he realized they were all females so he talked to his neighbour to see if he could bring his girls pigs over to meet with his boy pigs so he could get some babies. The neighbour agreed and so Ivor, the new farmer, loaded the girl pigs in his truck to visit the neighbour’s pigs.
That night he went back to pick them up and he asked his neighbour "How will I know if they are going to have little pigs?"
The neighbour said that they would start acting differently and that he could just tell.
So next morning he went and checked his pigs and they were just acting normally so he took them back to the neighbours again. Next morning same thing, no change so he took them back.
Next morning he was sitting at the table and he said to his wife "Honey, look out of the window and see if the pigs are acting differently."
She looked out the window and said "Well I don't know how differently you mean but 11 of them are in the back of the truck and one is in the front honking the horn!"
