A city person riding his bike through the countryside sees a farmer holding a pig up to a tree.
When he gets closer, it looks like the farmer is holding the pig so that it can reach an apple in order to eat it.
Excuse me, he says, but that seems incredibly inefficient. Wouldn't it save time to knock the apples onto the ground and let the pig eat them down there?
Sure, said the farmer, but what's time to a pig?
Get up. Go ride.
