Copper Wire.

After having dug to a depth of 10 feet last year, British scientists found traces of copper wire dating back 200 years and came to the conclusion that their ancestors already had a telephone network more than 150 years ago.

Not to be outdone by the Brit's, in the weeks that followed, an American archaeologist dug to a depth of 20 feet, and shortly after, a story published in the New York Times: "American archaeologists, finding traces of 250-year-old copper wire, have concluded that their ancestors already had an advanced high-tech communications network 50 years earlier than the British".

One week later, Australia's Northern Territory Times , reported the following: "After digging as deep as 30 feet in his backyard in Tennant Creek , Northern Territory, Lucky Bunji, a self-taught indigenous archaeologist, reported that he found absolutely f--k all. Lucky has therefore concluded that 250 years ago, Australia had already gone wireless." 
Just makes ya feel bloody proud to be Australian!------------------------------------------------------------
