This is the BBC.

Hello, I'm Robin Inz.

And I'm Brian Cox.

And having had a guest raven outstair Brian in a battle of which earlier this series today,

we're returning to Forner and looking at the behaviour of animals.

In fact, we were going to have a guest lepodon,

but unfortunately, it actually broke away from its leash and picked up Nicholas Parsons.

And there's just been dragging him all the way down Great Portland Street

with Paul Murr and running behind going,

Deviation, Deviation.

So, Brian, as we'll be talking about animals,

let's start off seriously.

It's like, what animal would you like to be?

I'd be a human.

Right, you're not doing this properly.

If you could be another animal like Adolfin, Alion or Alima.

No, but in episode three, series 17,

you said that I wasn't human.

So you can't have it both ways, can you?

Ah, physics says I can, actually.

Because using many world's theory, I'm going to demean you in two different universes.

So, just pretend for a moment.
