Had to share this knowledge
German scientists dug 50 meters underground and discovered small pieces of copper. After studying these pieces for a long time, Germany announced that the ancient Germans 25,000 years ago had a nationwide telephone network.
Naturally, the British government was not that easily impressed. They ordered their own scientists to dig even deeper. At 100 meters down, they found small pieces of glass and they soon announced that the ancient Brits 35,000 years ago already had a nationwide fibre net.
Irish scientists were outraged. They dug 50, 100 and 200 meters underground, but found absolutely nothing..... They concluded that the ancient Irish 55,000 years ago had cellular telephones......
