There's a point in this weeks episode where we find ourselves trying (and subsequently failing) to recollect the name of a particular procedure of chemical analysis.
It will be blatantly obvious when you reach that point in proceedings, and as it would also be hard to class it as a spoiler, I will tell you it's that one with a splodge on a bit of blotting paper.
Now the point I am trying to make is that it's not about the blotting paper (though you do know the one I mean don't you, in fact you are visualising it right now - I can tell by the expression on your face) but how we get to the blotting paper...
Because we should have been talking about Sounds That Can't Be Made. So please forgive me but, as you will hear, I just can't help it.
Now... can anyone tell me what I did with that seven and a half million dollars?
