Deep in the depths of mythic time, the people of the earth - the King James says "men" and, given their hubris and incompetence it's probably right - decided to show how great they were. So they built a tower that reached to the sky. They did it to make a name for themselves, so they were not scattered across the face of the earth.
Needless to say, given that kind of attitude, they were indeed scattered across the earth. And they were given diverse languages so they would never try that kind of thing again.
But one day the curse was reversed. The people came together, and found they shared a common language. And that language was American English. And they built a tower of gold lamé, sequins and platform soles. And they called that place Eurovision.
Sometimes you think all those languages were quite a good idea, after all.
