So this farmer was trying to get his sows a litter by driving them to a neighboring farm to breed with the prize boar. He'd heard that the sows would start rolling in the grass when they were pregnant. After the fifth trip to the neighbor with no luck, he asked his wife to look out the window to see if they were rolling in the grass yet. "Hell, no, they ain't rolling in the grass! Two of them are jumping up and down in the back of the truck and the third is sitting in the driver seat blowing the horn!"
