I've never quite understood what the point of journalists interviewing journalists was...
The idea is, I guess, that the conversational interview style of an interview is more accessible than a monologue from a location reporter when the news is too new to have packaged, or has no components suitable for packaging.
other favourites of mine that have been doing the rounds are one of the five live presenters breaking down on air after apparently arguing with her co-host for the whole morning.. and a bbc local radio phone-in with someone offering beef curtains for sale.. presenter doesn't twig for a couple of minutes!!
"Tell me the questions you want me to ask, and I'll ask them"
...or maybe you could use your brain, not just be a voice-on-a-stick and think of some yourself? Quite pathetic, I've heard two-ways with much less to talk about that have gone on far longer, and been more interesting.
