I would like to share this link with you all.

That website has a lot of Family Guy quotes. They are sorted in categories like: Character, Episode, Genre, etc. Very funny site.

Here are a few quotes that I like from Peter:

#1
Meg: I just want to kill myself I'm gonna go upstairs and eat a whole bowl of peanuts.
(Lois and Peter stare in silence)
Meg: I'm alergic to peanuts.
(Peter and Lois keep staring)
Meg: You dont know anything about me. (runs upstairs)
Peter: Who was that guy?

#2
Peter: Oh my god, Brian, there's a message in my Alphabits. It says, 'Oooooo.'
Brian: Peter, those are Cheerios
