Prolly Brian.... or Stewie cuz like the other person said, he sees things as adults do, yet he's a baby and no one knows what he's sayin.... or just thinks he's bein cute.

yea i agree..stewie is really smart and acts like an adult. He talks like an adult 2

Stewie is definetly the smartest. no one else in the town can plot to rule the world

Either Stewie or Brian, Stewie is more of an evil genious and Brian just seems to know just about everything else.

Stewie is a great mind....in the wrong way, well....everyone in there is a freak lol, Just great

well i would agree that stewie is the smartest ,but just to be different im gunna say peter lol

yeh stewie is prolly the smartest i agree

In a way Brian is smarter then Stewie when it comes to experience of course Brian always knows what he is doing and his attitude is wickid he is my favorite character. Stewie is smarter I guess because he "builds" all things like mind controll device, weather machine, ray guns and freezing guns bla bla bla. So I'm going to have to pick Brian because hes just to damn cool.
