A man from the city visiting a small farm saw a farmer feeding pigs in a most extraordinary manner. The farmer would lift a pig up to an apple tree and the pig would eat the apples straight off the tree. The farmer would move the pig from one apple to another until the pig was satisfied, then he’d start again with another pig.
After watching this for some time, the city man couldn’t resist saying to the farmer, “That’s the most inefficient method of feeding pigs I’ve ever seen! Think of the time you could save if you simply shook the apples off the tree and let the pigs eat them from the ground.”
The farmer looked puzzled. “What’s time to a pig?”
