The Wonderful Welsh have given us many things.
They gave us really cool stuff like powered flight, the theory of natural selection, radar, and the microphone.
They have given us such stars as Shirley Bassey, Sir Anthony Hopkins, Charlotte Church, Dylan Thomas, Tanni Grey-Thompson and that opera singing bloke from the Go Compare adverts.
But these all pale into insignificance* when compared to the WJEC French reading challenges website.
