Pigs

A farmer was worried that none of his pigs were getting pregnant. He called a vet and asked what he should do if he wanted more pigs. The vet told him he should try artificial insemination. The farmer, not wanting to appear stupid, answered okay and hung up the phone. Unclear on what the vet meant by artificial insemination, the farmer decided it must mean he had to impregnate the pigs himself, so he loaded all the pigs in his pickup and drove down to the woods and shagged them all.

The next day he called the vet again, and asked how would he know if the pigs were pregnant. The vet told him they would be lying down rolling in the mud, but when he looked out the window not even one was lying down. So, he loaded them up in his pickup again and drove them to the woods and shagged them all again. To his dismay they were all standing the next morning. So, again he loads the pigs in his truck drives them to the woods and shags them for the third time.

By the next morning the farmer is beat, so he asks his wife to hop out of bed and look out the window to see what the pigs are doing. She says "hmmm - that's weird, they are all in the truck and one of them is blowing the horn".
