In an extended scene from Volume 8:

After Chris tells Peter about the movie White Noise, before he tunes in Reagan, Peter is seen fiddling with the ham radio saying “Hello ghosts, come in ghosts. I am Peter Griffin. I am your friend. Don't be shy. Humphrey Bogart, Don Knotts, that kid I was supposed to be watching at the pool.”

In an extended scene from Volume 8:

After Lois says she thanks god Chris is healthy she says, “Isn't this a beautiful little girl?”
Glen: “Yeah but she kind of stinks.”
Lois: “Well no wonder, she's pooped herself.”
Glen: “EW! it's new car smell.”
Peter: “What?”
Glen: “That's what a new car smells like. It's disgusting.”
Peter: “Where are you buying you cars, Quagmire?”
Glen: “I buy them online at poopcars.com”
Peter: “Okay well I think I just solved the mystery.”

In an altered scene from Volume 8:

After Stewie says this was not a fruitful endeavor, instead of Brian saying he wanted to lick that up, he says “You don't see my ATM card in there do you?”
Stewie: “No. Do you want me to dig around and see if...”
Brian: “No, f_ _k it, it's fine”

Mistake by Writers:

Lois leaves a basket of stuff to help Glen with the baby and tells him if he has any questions they are right across the street.

Glen wouldn't have to cross any streets since obviously, the Griffins live next door to Glen and the Swansons live next door to Peter and Lois.

Continuity:

The paper Brian puts on the couch before he asks Stewie 'who the hell was that' has vanished when he says 'you cloned yourself?'

Animation Error:

Bitch Brian's jaw turns from white to pink after it falls off.
