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 the 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, Indian daily newspapers reported the following:
'After digging as deep as 500 meters, Indian scientists have found absolutely nothing. They have concluded that 5000 years ago, their ancestors were already using Bluetooth and Wireless technology.'
