Brian Griffin [to Stewie] You wanna know how to get women? There's only one place in town you need to observe.
[outside Quagmire's house]
Brian Griffin: Just watch.
Woman: I am not doing that, Glenn.
Glenn Quagmire: Come on beautiful, keep an open mind.
Woman: You're a sick man!
Glenn Quagmire: Hey keep it down, I don't want my neighbors seeing a fat, old, dirty whore screaming at me on my front lawn.
Woman: Whore?! Well, maybe I should come inside. [does so]
Glenn Quagmire: Well maybe you should.
Stewie Griffin: What the deuce? Why the hell would she respond so positively to such a negative comment? Unless... Brian, do women like it when you treat them like crap?
Brian Griffin: Well I-I don't know if you wanna be so black-and-white about it...
Stewie Griffin: WAIT! That's it! Women respond when you treat them like crap. Well, Olivia, prepare to meet a much darker Stewie.
