"Wisdom from the Elders" joke

It was autumn, and the Indians on the remote reservation asked their new
Chief if the winter was going to be cold or mild. Since he was an Indian
Chief in a modern society, he had never actually been taught any of the
old secrets, and when he looked at the sky, he had no clue as to what
the weather was going to be.
Nevertheless, to be on the safe side, he replied to his tribe that the
winter was indeed going to be cold and that the members of the village
should collect wood to be prepared. But also being a practical leader,
after several days he got an idea. He went to the phone booth, called
the National Weather Service and asked, "Is the coming winter going to
be cold?" "It looks like this winter is going to be quite cold indeed,"
the meteorologist at the weather service responded. So the Chief went
back to his people and told them to collect even more wood in order to
be prepared.
A week later he called the National Weather Service again. "Is it
going to be a very cold winter?" "Yes," the man at National Weather
Service again replied, "it's 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. "Are you
absolutely sure that the winter is going to be very cold?" "Absolutely,"
the man replied, "it's going to be one of the coldest winters ever."
"How can you be so sure?" the Chief asked. The weatherman replied, "The
Indians are collecting wood like crazy."
