A farmer's cow gave birth to twin bull calves. The farmer was delighted as bull calves are worth more than a cow calf.  Since he had two he decided to sell one for the work of the Lord once it was fully grown.

However one of the calves soon grew sick, and then sicker until one day the farmer came into the house one day looking sad.

He looked at his wife and said, "You'll never guess what's just happened? The Lord's calf is dead!"
