Brian: I mean I was having fun, making new friends, getting laid all the time, sleeping like a rock - but you made the call. You unilaterally decided I was better off a bitter alcoholic failure who could only hang out with a baby.
Stewie: Hey! We have fun.

Stewie: I've been approaching this far too intelligently. He's an idiot, so this shouldn't be hard at all! Hey Brian, you want to go see Doctor Hartman and get that procedure where you get two weiners?
Brian: Whoa, hell yeah! That way when I watch Black Swan, I can aim one at that Natalie Portman, and aim the other one at -
Stewie: Yes, yes, yes, we all know who the other one was.

I forgot Yelp was a weapon for dumb people, you taught me something today Brian.

Stewie

Stewie: Because right now, you're about as useless as Black Widow is to the Avengers.
Captain America: So what's your superpower again?
Black Widow: I can kick.
Captain America: Right…so, uh, who else here can kick? Hulk stop being nice.

Chris: Mom, is dad gonna die?
Lois: Well Brian's the one with the brain tumor.

Brian: Winning!
Peter: Haha, remember somebody said that?

Lois: Doctor, do you think the brain tumor could have anything to do with Brian's recent behavior?
Doctor: Hmm, I haven't heard of brains being linked to behavior, but I suppose anything's possible.

Doctor: I did a CAT scan
Peter: On a dog, haha.
Doctor: Haha, we laughed about that too.

Doesn't it make more sense…to kill her?

Peter

Brian: Bazinga!
Peter: Haha, like what the guy scientist says. Brian, say something else from TV!
Brian: Watchu talkin bout Willis!?
