Brian: I don't watch that show.
Jasper: I wasn't talking about the show. Ooh, I'm nasty! (Imitates foghorn) Someone put me out to sea!

Hey, how about a little less questions and a little more shut the hell up

Meg: Wow, Brian! Have you lost weight? You gotta tell me your secret!
Brian: Here's a hint: Put down the fork!

Brian, it's moments like this that make me sad you're gonna die fifty years before I do

Rehab Counselor: I don't think you're an addict, I think you're an idiot.
Peter: Yeah, well I don't pay you to think, hot lips, in fact, I don't pay you at all...

Brian: What are you doing here [at rehab]?
Peter: I'm on vacation. Oh, and if anyone asks, I'm also on smack

Peter: Oh, Chris, that's just fancy-talk for Sexified

Quagmire: Oh, yeah? (to Brian) How good are you?

Quagmire: You mean three Filipino women. (Brian stares blankly) NOOOOO!
