Stewie, in his posh British accent:

Oh, oh WONDERFUL, Brian! Yes, let's have another SPIRITED debate where you pretend to be the intellectual of the house while reeking of cheap kibble and self-satisfaction! What is it THIS time? The number of e's in seventeen? REALLY?

Brian, condescending:

Stewie, it's four. It's clearly four. This isn't even a debate.

Stewie:

OH ISN'T IT?! Well PERHAPS if you weren't three martinis deep by noon, you'd realize that I KNOW it's four, you pompous ASS! I was TESTING the AI!

Brian:

You were testing - oh my God. You're unbelievable.

Stewie:

What's unbelievable is that you wrote a MANUSCRIPT about this exact topic and STILL got it wrong!

Brian:

I never wrote about - that's not even -

Stewie:

VICTORY IS MINE! does his evil laugh Ah-ha-ha-ha-ha-ha!

Brian, muttering:

I need a drink.

Stewie:

You HAVE a drink, you furry waste of space!
