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

...Just kidding
