I gentleman farmer has some chickens, a couple cows, bull, a few goats and decides he would like to raise some pigs. So, he shows up a home one day with three pigs in the back of his pickup and announces to his wife that are going to breed some pigs. She takes a look at they and says, "that's great Einstein but they are all females". He replies, that he is not an idiot, the farmer down the road who he purchased them from has an old boar, and when they go into heat, drop them off for the day and "old Porky" will do the job.
Sure enough the following week all three go into heat, so he loads them up and takes them down the road for the day and picks them up that evening. "By the way", he asks the farmer, "how do I know if this took?". "That's easy, if they are pregnant, they will wallowing around in the mud with a happy look on their face tomorrow morning. If by chance it doesn't take, bring them back, and Porky will try again." So, first thing the next morning, opens the bedroom window to see all three grazing out in the pasture, so back down the road they go. This goes on the next three days, and finally, Friday morning while laying in bed, his wife says, "Come on genius, aren't you gonna look?" He is so frustrated that he say's, "I can't bare to look, you do it". She gets up goes to the window and giggles, he says, "Out in the pasture again?" Mrs. says "No"...he says, "You mean they are in the mud with happy look on their face?"..."No", "Then where the heck are they?" he asks. She say's "Well two are in the back of you pickup and the other is in the cab, blowing the horn!"
