There was once a man from the city who was visiting a small farm, and during this visit he saw a farmer feeding pigs in a most extraordinary manner. The farmer would lift a pig up to a nearby apple tree, and the pig would eat the apples off the tree directly. The farmer would move the pig from one apple to another until the pig was satisfied, then he would start again with another pig. The city man watched this activity for some time with great astonishment¹. Finally, he could not resist saying to the farmer, "This is the most inefficient² method of feeding pigs that I can imagine. Just think of the time that would be saved if you simply shook the apples off the tree and let the pigs eat them from the ground!" The farmer looked puzzled and replied, "What's time to a pig?"
