Aw, Quagmire got away with it and learned nothing -- that's great.

Peter

You got a good body man, why do you hide it under your robe?

Peter

Thanks for the liver, kid. Here's to you.

Frank

Did you hear about your ex-husband yet? He's had a procedure.

Stewie

Quagmire: Where do you get off?!
Stewie: Pretty much everywhere I hear. Fat man's right -- they're making this easy.

Don't think of it as 20 years -- think of it as two 10 year olds, you sick freak.

Peter

Still don't want your family to know? Nothing says no regrets like hiding it from those you love.

Sean [to Fiona]

You know I'm carrying three handguns and the metal detectors picked up nothing?

Peter

My misguided carnal instincts are the results of being raised by a sexual deviant.

Quagmire

Doctor: How do you feel?
Quagmire's Mom: Horny. Really horny. Could you put him back so I can push him out again?

Stewie: Which is hugging someone really hard with your legs.
Brian: Nope.
Stewie: Oh, well you'll tell me if I get it right?

Does this mean you're going to move to Europe to make movies?
