Even though cars get worse gas mileage than two decades ago, they actually have become much more efficient.

The fields were grown over with weeds, the farmhouse was falling apart, and the fences were broken down. During his first day of work, the town preacher stops by to bless the man's work, saying, "May you and God work together to make this the farm of your dreams!"

The farm house is completely rebuilt and in excellent condition, there is plenty of cattle and other livestock happily munching on feed in well-fenced pens, and the fields are filled with crops planted in neat rows. "Amazing!" the preacher says. "Look what God and you have accomplished together!" "Yes, reverend," says the farmer, "but remember what the farm was like when God was working it alone!"
