Frozen cows

It had been a bitterly cold night and the farmer went out to round up his cows for milking, only to find them all frozen solid, motionless; like statues.
He never thought anything like this could happen.
With his entire livestock gone, how would he make ends meet? He sat with his head in his hands, trying to come to terms with his impending poverty.
Just then, an elderly woman walked by. "What's the matter?" asked the old lady.
The farmer gestured toward the frozen cows and explained his predicament.
Without hesitation the old woman smiled and began to rub one of the cows noses. After a few seconds the cow began to twitch and was soon back to normal and chewing the cud.
One by one, the old woman defrosted the cows until the whole field was full of healthy animals.
The farmer was delighted and asked the woman what she wanted as a repayment for her deed.
She declined his offer and walked off across the field.
A passer-by who had witnessed the whole thing approached the farmer.
"You know who that was don't you?" he asked.
"No" said the farmer "who?"
