[Short pause; Stewie then throws his guitar on the floor and walks out]
Stewie: Go fuck yourself.

Stewie: Hey, New Brian. Oh, I see you're having pie. You know, pie isn't really pie without Cool Hwhip.
[Stewie doesn't get a reaction from New Brian.]
Stewie: Everything's better with Cool Hwhip.
[Still no reaction.]
Stewie: Did you hear what I said?
New Brian: Yeah, what about it?
Stewie: It doesn't bother you the way I pronounce it? "Cool Hwhip?"
New Brian: No, why would it?
Stewie: Cool Hwhip. I'm putting emphasis on the H.
New Brian: Sounds right to me.
Stewie: Nothing ever bothers you, does it?
New Brian: No, not really. I like everything.

Hitler: These filth are making a mockery of our Reich! Execute them! [the solders cock their guns, ready to shoot them, but Hitler interrupts them] Unless...

Hitler: Unless they can sing a charming musical number.
[Stewie and Brian smile at each other as music starts playing. A pair of hats and canes are tossed at them]
Stewie & Brian: Whenever-
Mort: [stands on the return pad] Damn it, will you two just get in the fucking time machine?!

Stewie: All right, Brian, we'll go. But don't touch anything while we're there. Even stepping on a mosquito can cause a chain reaction that drastically alters the present.
Brian: Really?
Stewie: Nah. You can do whatever you want.

Peter: Brian, can I see that paper for a sec? [Brian hands him the paper] Huh, that's odd. I thought that would be big news.
Brian: You thought what would be big news?
Peter: Well, there seems to be an absence of a certain ornithological piece. A headline regarding mass awareness of a certain avian variety.
Brian: What are you talking about?
Peter: Oh, have you not heard? It was my understanding that everyone had heard...
Brian: Heard what?
Stewie: Brian, don't! [Peter puts the record on and starts dancing and singing]

Arianna Huffington: What is yours, Snoopy?

You have to do some of the work yourself. That's why there are 50 blank pages.

Bill Maher: Help is such a strong word. How does this help people with cancer or in Darfur?
Brian: Well it's not really for that. It's for like, if you want a car or something.

Brian: Wish it, Want it, Do it.
Stewie: Love it!
