After digging to a depth of 100 meters last year, Russian scientists found traces of copper wire dating back 1000 years, and came to the conclusion that their ancestors already had a telephone network one thousand years ago.
So, not to be outdone, in the weeks that followed, American scientists dug 200 meters and headlines in the US papers read: "US scientists have found traces of 2000 year old optical fiber, and have concluded that their ancestors already had advanced high-tech digital telephone 1000 years earlier than the Russians."
One week later, the Sowetan newspaper from Johannesburg, South Africa reported the following: "After digging as deep as 500 meters, Zulu scientists have found absolutely nothing. They concluded that 5000 years ago, their ancestors were already using wireless technology."
