The Parable of the Apple Eating Pig

A traveller was driving along a country road when he spied a farmer in an apple orchard. The farmer was holding up a pig to the lower branches of an apple tree so the pig could eat the apples hanging there. The traveller pulled over and remarked, "Wouldn't it save time to shake the apples off the branch and let the pig eat them off the ground?" The farmer pondered this for a moment and queried, "Yes, but what's time to a pig?"
