Dr Karl

You've then got muscular tension involved and you'll drop your face into some version of the RBF or the resting bitch face.

And then you've got your furrows, you know, narrowing up and the mouth trembling and dropping and all of these associated with big emotions.

That's a mystery as to why we cry sometimes with happiness.

You're laughing so much.

I'm guessing it's some sort of involvement.

Now, this is where my knowledge of the neuroanatomical innovation of the lacrimal glands with regard to emotion is deficient.

I failed you on that one.

That's all right.

But I'm reckoning that that is part of it, that you are for some reason activating them and I don't know why.

Thank you.

So let me get this straight.

So what sort of biscuits are you doing the dunking with?

I love breaking them into two halves, so that way you get twice as many opportunities to dunk.

Yeah, keep going.

And the oval ones, which have got no sweet stuff on them at all.

Now, this is a deep topic that you're getting into.

Now, you're saying that the tea causes the biscuit to absorb more liquid.

You are so close, mate.

Okay, so firstly, the person who actually won an Ig Nobel Prize on this is Len Fisher.

And he did a lot of research on tea dunking, as I did myself in Why Belly Button Fluffy's Blue and all that sort of stuff.
