E4 are suspending their usual programming for that day (only until 7pm mind so not brave enough to suspend the premiere episodes of American comedies like Big Bang) and there will be some young bloke called Darren sitting in front of/operating a switch . AIBU to assume some will tune in anyway just to see what he gets up to.
After all there are plenty of viewers who watch Big Brother live feeds when there is nothing really much happening. And it also assumes that no young people have jobs at all and just watch tv all day. Strange idea.
