(Peter is seen walking into a stem-cell research facility, and later walking out all cured)
Peter: How long was I in there?
Guard: About five minutes.
Peter: Why are we not funding this!?

Lois: Peter, have you seen Brian?
Peter: (with his back to her, his voice is muffled) No, Lois. I have not.
Lois: Well, I haven't seen him since this morning and I--what is that on your head?
(Peter turns to reveal Brian duct taped to his face)
Peter: It's a mustache, Lois! What, you've never seen a mustache before?!
Brian: (calmly)Lois, would you mind calling the police or something?
Peter: Quiet, mustache!

(looking at Mustache Aficionado Magazine) Wow, look at these men. What class! What grace! And all because of a little upper lip hair. Lois, I am gonna grow a mustache. And I'll have it made like the Monopoly guy. Except when he goes directly to jail.

Peter: Black mail call!
Lois: Peter, you were supposed to collect Cleveland's mail, not go through it.
Peter: Lois, black people aren't like you and I, and I find that hilarious!

(after the the judge rules in favor of McBurgertown industries)
Peter: What!? Hey c'mon, that's not fair!
Judge: Well Mr. Griffin, what did you expect? They have a hundred lawyers. And you tried to bribe me with a subsription to Grape Soda Today, which I already have!

Stewie: Well Brian, you've lost your bet. I, or rather my alter-ego Zack Sawyer, am currently the most popular boy at James Woods High.
Brian: Well, Stewie, you got the best of me on this one, congratulations. I guess you'll be hanging up your wig now?
Stewie: Oh no Brian, I'm enjoying myself too much. Do you know I have a date with Connie D'amico this Saturday night at Anal Point?
Brian: Ah, I've heard about that place.
Stewie: Really? What's it like? Because I have no idea.
Brian: Well, uh... I suppose if you imagine it like a parking space that you think "gosh, there's no way I'm gonna be able to fit in there." But then you fold in the side view mirrors, and sure enough, well, look at that.
Stewie: Well, in that scenario, it sounds like I'd rather be the parking space than the car.
Brian: Yeah, that's what I always guessed.

Stewie: Hey, Brian, knock knock!
Brian: Who's there?
Stewie: (whispering) Two friends, building a house together.

Lois: Peter, Meg's been down there an awfully long time.
Peter: Boy, you cannot wait to criticise her at every turn, can you, Lois?

(about Meg's wedding dress) Look at her fat shoulders in those spaghetti straps. It's like bread baking around twine!

Stewie

I can set you up with one of my friends. Oh wait, I don't have any friends. Well I can set you up with dad! Dad, will you be interested in dating Meg?

Chris

See, look Meg, he just walked out on you. He's a bad man, like Jodie Foster.

Peter

Stay away from my daughter you possible rapist!

Family Guy Season 6 Quotes

You can kiss the lower part of the back of the canister that is my body!

Cleveland (R2-D2)

Death Star Officer 1: Any attack made by the Rebels against this station would be a useless gesture, no matter what technical data they've obtained. This station is now the ultimate power in the universe.
Stewie (Darth Vader): That is fantastic! Terrific work! So no weaknesses at all, huh?
Death Star Officer 1: N- (considers) no.
Stewie (Darth Vader): You, uh, you hesitated there. Is there something I should know?
Death Star Officer 1: No, it's virtually indestructable, like 99.99 percent.
Stewie (Darth Vader): Uh...OK, wouldn't be doin' my job if I didn't ask what's the .01?
Death Star Officer 1: Well, I- I mean, there's this little hole, it was kind of an aesthetic choice by the architect, and if you shoot a laser into this hole, uh, the station blows up.
Stewie (Darth Vader): Whoa, whoa, whoa, whoa, whoa, that sounds like a pretty big design flaw there.
Death Star Officer 1: No, no, no the hole's only two meters across.
Mayor Adam West (Grand Moff Tarkin): Well, that's no bigger than a womp rat.
Death Star Officer 1: Exactly. And even to get within range of it, you have to skim along this whole trench, it's not a big deal.
Stewie (Darth Vader): Well, I mean, I mean, can't we board it up or, you know, put some plywood over it or something?
Death Star Officer 1: Well, that would look terrible! I mean, we got to think about re-sale.
Stewie (Darth Vader): Re-sale? Wh-what are you talking about? This property is right above Sunset, the value's only gonna go up.
Death Star Officer 1: Lord Vader, your inside references to the Los Angeles real estate market haven't given you the clairvoyance to turn a profit on that condo in Glendale, nor has it-
(Vader begins choking him with the Force)
Stewie (Darth Vader): I find your lack of faith disturbing. That property is in a prime location, twenty minutes to the beach, twenty minutes to downtown!
Death Star Officer 1: (choking) There's nothing to do downtown!
Mayor Adam West (Grand Moff Tarkin): Enough of this! Vader, release him.
Stewie (Darth Vader): As you wish. (releases the officer, who collapses on the table, gasping for air) All right, so we gonna plug up that hole?
Death Star Officer 2: Yeah, we can get it done tomorrow if price is no object.
Stewie (Darth Vader): Eyuuuuh...
Death Star Officer 2: We'll get estimates.
Stewie (Darth Vader): Yeah, get estimates, yeah ha, yeah, yeah ha ha, yeah.
