Harrington: Hi I'm Darth Harrington of "Darth Harrington's Intergalactic Proton Powered Electrical Tentacled Advertising Droids Emporium and Moon Base"!

Brian: You know, Connie, I think I have a theory about why you're such a bitch.
Connie: Excuse me?
Meg: Brian, let's just go.
Brian: No, no, no, no, no. Now hang on... hang on, Meg, hang on. You see, Connie, you're popular because you developed early and started putting out when you were 12. But now you can't stand to look at yourself in the mirror because all you see is a whore. So, you pick on Meg to avoid the inevitable realization that once your body's used up by age 19, you're going to be a worn-out, chalky-skinned burlap sack that even your step-dad won't want. How's that? Am I in the ballpark?

Quagmire: (smugly) Huh, yeah, that's just as fun.

Getting alcohol when you're underage isn't as easy as Obama's daughters make it look.

Peter

Joe: I'm here to revoke your driver's license.
Peter: What? Why?
Joe: We got reckless driving, disturbing the peace, plus the driver of one of those other cars was a virgin whose hymen was busted by the airbags, so rape.

Brian: Gosh, this is a... lovely home Tracy.
Stewie: That's so weird. It smells like there's a cat, but I bet there's no cat.
