This landed in my e-mail inbox this morning (thanks, Dave!):
After digging to a depth of 100 meters last year, Russian scientists found traces of copper wire dating back 1000 years, & came to the conclusion that their ancestors already had a telephone network 1,000 years ago.
So, not to be outdone, in the weeks that followed, American scientists dug 200 meters and headlines in the US papers read. . . . “U.S. scientists have found traces of silica, indicating 2,000 year old optical fibres, & have concluded that their ancestors already had advanced high-tech digital telephone 1,000 years earlier than the Russians.”
One week later, the Canadian newspapers reported the following. . . . “After digging as deep as 500 meters, Canadian scientists have found absolutely nothing. They have concluded that 5,000 years ago, their ancestors were already using wireless technology.”
