[Nick Naylor and his son arguing about ice cream]

Joey:
So, what happens when you're wrong?

Nick:
Well, Joey, I'm never wrong.

Joey:
But you can't always be right.

Nick:
Well, if it's your job to be right, then you're never wrong.

Joey:
But what if you are wrong?

Nick:
Okay, let's say that you're defending chocolate and I'm defending vanilla. Now, if I were to say to you, "Vanilla's the best flavor ice cream", you'd say …?

Joey:
"No, chocolate is."

Nick:
Exactly. But you can't win that argument. So, I'll ask you: So you think chocolate is the end-all and be-all of ice cream, do you?

Joey:
It's the best ice cream; I wouldn't order any other.

Nick:
Oh. So it's all chocolate for you, is it?

Joey:
Yes, chocolate is all I need.

Nick:
Well, I need more than chocolate. And for that matter, I need more than vanilla. I believe that we need freedom and choice when it comes to our ice cream, and that, Joey Naylor, that is the definition of liberty.

Joey:
But that's not what we're talking about.

Nick:
Ah, but that's what I'm talking about.

Joey:
But … you didn't prove that vanilla's the best.

Nick:
I didn't have to. I proved that you're wrong, and if you're wrong, I'm right.

Joey:
But you still didn't convince me.

Nick:
Because I'm not after you. I'm after them.
