Brian Cox

It's key childhood memory for many to be walking around the zoo and getting to the monkey enclosure and then seeing that something is going on.

You're just a young, innocent child and you say, Mummy, what's that monkey hanging in that tyre doing?

And she goes, look away, Brian, look away!

LAUGHTER

There's nothing of interest here.

But, Mum, I'm really interested.

There's all things going... No, let's go to the chinchilla enclosure!

But, Mother, I'm left with questions unanswered that might damage me in the future.

And I'll only be able to deal with particles, not living things.

Psychotherapists actually do believe that it is this experience that Brian and so many of you have had in the zoo that can lead to a rubber fetish, though only if the rubber has a six-inch tread.

But today... I love the way that rippled around, because...

People were reading different images in and surprising yourselves.

I think most people are just questioning a six-inch tread.

That's enormous.

What kind of tyre is that?

That's just a tractor, isn't it?

Not six inches.

That's two or three inches at most.

No, I don't know anything about cars.

This is going to make no sense now, but anyway.
