Then there's the story of the on-the-street reporter who, at the turn of the millennium, went out looking for comments. His question was simple: What was the greatest invention of the last thousand years? But he kept getting answers like the telephone, or the computer, or open-heart surgery ... and he was looking for something bit different.
Tired of asking ordinary people, he spied a wino and ent over to ask him the question.
"Why that's simple, son," said the wino. "The greatest invention of the last thousand years has to be the Thermos bottle."
Taken aback, the reporter started to get angry. "What's so great about a Thermos bottle, old man? All it does is keep hot things hot and cold things cold. What makes that so great?"
"Think about it, son, think about it," said the old man. "It keeps things hot in the winter, and it keeps things cold in the summer. How do it know?"
