Welcome to episode five of the QS cases of Rutherford and Fry, the lost producer.

Yes indeed. So this is a program that we made that was sent in by our producer.

As it turns out, our producer just, I think that she just didn't want to make a program and

got lost in the corridor and left it all to us. Yes. We did have the honor, the privilege of

actually being producers and various elements of these show. And doing the experiments on her

rather than having them done to us. Yes. So we have to apologise in advance because some of

the sound recording, particularly by me, is a bit shaking. It turns out producers know exactly

what they're doing. And that's the specialist expert job. I know. I know.

Rather than us just fooling around in front of the microphones for hours on end.

Our job is actually, as it looks though, let's do the informational bits.

Every day, silence mysteries, things you've always wondered about.

I don't know why I'm putting that voice on, doesn't it? I like that voice.

That's your really serious BBC 4 presenter voice. It's the one I put on when I try and pretend to be clever

than I am. It's pretty clever already. Anyway, we've got a special treat because this is the end

of the series. I don't know if a treat is the right word to describe it. I'm quite anxious about this.

What is it? A blooper's real. Yes. It turns out, dear podcast listeners.

That the process of making this programme is somewhat littered with mistakes.

Yes, it's not optimised for efficiency. And Michelle, our brilliant producer.

Who's the only professional person of this tree? It holds the whole thing together, basically.

But she has collected some of the bloopers from the last few series and as a special treat,

if you listen to the end, you'll hear them after our lawyers have cleared them.
