"Is it going to be a very cold winter?"

The Chief again went back to his people and ordered them to collect every scrap of wood they could find. Two weeks later he called the National Weather Service again.
"How can you be so sure?" the Chief asked.
The weatherman replied, "The Indians are collecting wood like crazy!"
