A traveling salesman is driving down a country road when he comes across a farmer who is standing in his orchard, hoisting pigs into the apple trees with ropes. He stops. What are you doing? the salesman asks. I'm feeding the pigs, answers the farmer, incredulous that someone could ask a question with such an obvious answer. Well, says the salesman, why don't you let the apples fall to the ground, gather them up in baskets, and feed the pigs that way? The farmer ponders, then says, Hmmmm. Yes, I guess I could do it that way. But what would be the point? The salesman is a bit exasperated: Well, it would save time, wouldn't it? The farmer ponders again. Yes, he says after a pause, I guess it would save time. But what's time to a pig?
