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 fibers, and have concluded that their ancestors already had advanced high-tech digital telephone 1000 years earlier than the Russians."
One week later, the Arab newspapers reported the following: "After digging as deep as 500 meters, Arab scientists have found absolutely nothing.
"They have concluded that 5000 years ago, Their ancestors were already using wireless technology."
