A husband and wife were driving down a country lane on their way to visit some friends. As they came to a muddy part of the road, their car got stuck.

While trying to get the car out by themselves, they saw a farmer coming down the lane, driving
some oxen. He stopped when he saw the couple in trouble and offered to pull the car out of the mud for $20. They accepted and minutes later the car was free.

The farmer turned to the husband and said, "You know, you're the tenth car I've helped out of the mud today."

The husband looked around at the vast fields and asked the farmer, "When do you have time to plow your land? At night?"

"Nope," the farmer replied, "Night's when I put the water in the hole!"
