An old man walks up to a newsstand. He buys a newspaper, looks at the front-page and throws it right into the trash-can next to the stand. The next day, he does the same: He buys a newspaper, looks at the front-page and throws it into the trash. And the next day he does the same. And the next, and the next.
Eventually, the sales-guy asks the man why he keeps doing that: Buying a newspaper, looking at the front and throwing it away.
I understand this man.
