Well this was strange. We were about to watch The Great british Bakeoff an extra slice which had been recorded to the Sky box. It asked for our PIN no which we had forgotten. Tried 3 times and got locked out of the programme. Also recorded and that I have not finished watching was the documentary on Robert Mapplethorpe. PIN not required funnily enough so we put it on and there on the screen was Robert with a bull whip stuck up his bum. I wonder how they decide which is of an adult nature and is PIN protected?
