How does this job work - those guys who do the voiceover links between programmes? They must be live, because sometimes they fluff it up, and you they must watch at least a little bit of the programmes because they sometimes make sarky comments about what just happened.
But they can't sit there all day watching TV, rousing themselves every 30 minutes for a not-so-sparkling quip. So how does it work? What else are they doing all day? Who are these people?
