Reliable forecast

It's fall & the Indians on the Reservation asked their new chief if winter was going to be cold. Since he was a modern chief, he didn't know the old ways & when he looked at the sky, he couldn't tell what winter was going to be like. So to be safe, he told his tribe that winter was going to be cold & they should collect firewood to be prepared. But being practical, he called the Weather Service &... asked if winter was going to be cold?' 'It looks like it's going to be quite cold,' the meteorologist said. So the chief again told his people to collect more firewood.

A week later, he called the Weather Service again. 'Does it still look like it's going to be a very cold winter?' 'Yes,' was the reply again, 'it's going to be a very cold winter.' The chief again went to his people & ordered them to collect every scrap of firewood they could find. 2 weeks later, the chief called the Weather Service again. 'Are you absolutely sure that winter is going to be very cold? 'Absolutely,' the man replied. 'It's looking more and more like it's going to be one of the coldest winters we've seen.' 'How can you be so sure?' the chief asked. The weatherman replied, 'The Indians are collecting a ton of of firewood.'
