Oh Lionel, glad you could make it. Can I get you a drink?

Yeah, something soft; I'm driving.

Parking's an absolute nightmare around here, isn't it? You have to reverse into the tiniest of spaces.

Still, I managed it. I mean, parking's not exactly brain surgery, is it?

And I should know.

Why is that, are you a doctor?

Careful. Not a doctor. I'm a brain surgeon. Big difference. BIIIG difference.

Yeah, I actually know a joke about this.

What's the difference between a doctor and a brain surgeon?

One's not exactly brain surgery, the other IS brain surgery.

So, what do you, guys, do?

I'm an accountant.

Oh, that's good. Yeah, I COULD DO WITH an accountant.

Filling in those tax forms can get really confusing, can't it?

Still ...

... it's not exactly brain surgery, is it?

I mean, brain surgery, believe me, is very complex.

Are you an accountant, too?

No, I work for charity.

Oh, that's a very selfless job, isn't it. I really admire you.

I don't think I could ever do what you do.

I say that because it's emotionally draining, not because it's hard.

I mean ...

... it's not exactly brain surgery, is it?

Which, as a brain surgeon, is what I do.

Lionel, here's your drink.

Lionel's a brain surgeon, you know.

Yeah, he mentioned it.

Oh Jeff, they kept you late at the space center?

As always, yeah.

Have you met Lionel?

No, hello Lionel.

So Jeff, how do you EARN A CRUST?

I'm a scientist. I work mainly with rockets.

It's pretty tough work. What do you do?

Well I don't mean to BOAST, but I'm a brain surgeon.

Brain surgery?

Not exactly rocket science.
