Family Guy Presents Stewie Griffin: The Untold Story2005

Stewie Griffin:
[looking at Rupert, whose leg has been sewn back on] I say, what happened to his leg? Oh wait, now I remember.

[flashback to Brian and Stewie at the kitchen table]

Brian Griffin:
You are really gonna sit there with a straight face and tell me a flat tax doesn't favor the wealthy.

Stewie Griffin:
Not one bit. And it saves millions of man hours that the complexity of the current tax code wastes, which you would realize if you weren't retarded.

[Brian takes Rupert, cuts off his leg, and eats it]

Stewie Griffin:
Hey, give him back - stop that - what are you doing? Give me back his leg!

Brian Griffin:
[smirking] Oh, you'll get it back.
