When we heard that there was a man in Wales living on his roof, we had to take a look. Not sure why. In fact, it means that tomorrow we have a 7 hour round trip for 1 hour of filming. When I called him, his accent was so Welch that I could hardly understand him. I'm not talking Imogen from Big Brother. I'm talking S4C. But anyway, this means that our web-celeb is none other than Rick on the Roof. He better be hilarious.
