Peter: Shut up, Meg!
Lois: Peter!
Chris: Dad!
Brian: You're back!
Meg: [dejectedly] Yay.

We should not rule out the Predator having been the farter.

Chris

Lois: Who threw out my sequined top?
Stewie: You're 43, accept it!

[to his feral self] Don't listen to that Peter! That Peter is a liar! Run, be free! They will enslave you! [makes random grunting noises]

Joe: Here you go guys, first time in a while I've had wood in my lap.
Quagmire: Are we supposed to laugh at that? Because it's upsetting.

Peter: You know, we saved so much trouble not flying commercial I think we came out ahead.
Joe: Sure. Drive right up to the plane.
Peter: Exactly. If we went to Logan, that plane wouldn't crash for another hour at least. [plane crashes behind him] Oh, they made pretty good time!

Hang on, you guys! I don't know if I can pull out of this, giggity!

Quagmire

Peter: A private plane? How'd you swing that, Quagmire?
Quagmire: Let's just say I walked in John Travolta with not-Kelly-Preston.

Quagmire: Do like me, say "oui oui!" and tell them you're a friend of Bill Maher's!
Bill Maher: That's how you'll get to watch them pee in Canadian nudie bars!

I'd even go so far as to say that a Canadian strip club is the most magical place in the world.

Quagmire

I always wanted to go to Canada, but then South Park went so we couldn't go.

Peter
