I just happened to be flicking through the digital channels this morning and came across E4 or something, which was showing Big Brother live. Thing is, they'd be talking about bugger all and the dialogue would cut out and all you could hear was planes flying over and birds singing. Then the talking came back and then went again, this happened several times. The cameras didn't stray from the 'action'; you could see the people talking but could hear a Chaffinch. What's the point of that?
