Continuity: In the scene where Lois and Peter are at the historical auction, when Lois stops to talk to her friend the person standing next to her friend is wearing a green suit. In the very next shot he is wearing a black suit and vest.

Continuity: When Peter and Brian are lounging in the pool, Peter's beer can appears on his stomach between shots.

Continuity: When Peter has become cultured and is talking to Coco and Jonathon, Jonathon's suit changes colour from brownish-green to grey.

Audio problem: When Peter introduces the pope to his friends at work, and he is saying "Remember when we got that stripper for Charlie and it turned out to be his son? I think this is gonna top it" or something along those lines), Peter's mouth very obviously does not sync up with the words being said.

Continuity: In the first shot of Peter and Francis at the baseball game, there is a girl in a green dress sitting behind them. In the next shot there is a guy in a cream shirt sitting behind them.

Factual error: At one point, Peter's father tells Lois "Maybe you won't go to Hell after all. Maybe you'll just be sent to Purgatory with all the unbaptized babies." Catholics believe that unbaptized babies are sent to Limbo, not Purgatory, and a fanatically devout Catholic like Mr. Griffin would know that.

Continuity: When Meg is putting down traps for Joe, she puts down a lot. Then when the Griffens leave and the giant rat comes, there are only a few. Then when Joe says "bring it on," there are a lot again.

Continuity: When the government people are looking at the missiles spelling 'Happy New Year', the 'Y' in 'Year' changes distinctly between shots.

Continuity: When the family comes out of the house after the apocalypse and finds Peter impaled on a "gag" fence, watch the way the fence is stuck in him. At first the thin side is up and down, meaning the band going around Peter would attach to the wider side of the fence. When he takes it off, the band is attached to the thin edge, which makes the previous shot of him impaled impossible.

Continuity: The position of the hole on the leg of Meg's pants changes. In the scene where Meg is putting the mouse traps around Joe, the hole is on the right side. When they arrive at the house with Randy Newman and Meg is telling Peter that the Twinkee factory in Natick may not even exist, the hole is on the left side. This happens again throughout the episode.

Continuity: When Peter drinks the water after having all the dehydrated meals, he expands. Then in the next 'shot' he is much bigger, even though there is no time for him to have expanded further.

Continuity: When the Griffins are leaving Quahog and Meg is putting mouse traps down for Joe, the traps disappear and reappear in different spots than she put them during the rest of the scene.

Continuity: After Lois accuses Stewie of peeing on the carpet, he asks her to bend down and slaps her with a glove. The glove remains in his hand in that cut, is still there when there is a wide shot of Peter, Stewie, Lois and Brian (you can just see it next to his trousers in his hand), but when it cuts back to Stewie and he starts on about "the outrages" etc, it is gone (the cut is instant, no time for him to put it back in his pocket). A common error, this one just struck me as strange, because the sandwich Stewie threw at Lois is there the entire scene.

Continuity: When Stewie has been picked up by Lois and is being kissed by her, Brian freaks out. When you first see Stewie and Lois, Stewie's hands are on her arms, next shot, they're on her shirt.

Continuity: When Spooner St. is announced as the parade's winner, Lois and Loretta hug. In the next shot, they are both waving their hands in the air.

Other: At the end, Brian says, 'I guess some mysteries are better left unsolved' and everyone else murmurs their agreement, yet Bonnie is heard saying, 'Peter's got a point'. She should have said Brian.

Continuity: In the end of the episode whilst the families are eating lunch at the picnic table there is a lot of plates of food and glasses on the table. Towards the end of the scene Brian says "I guess some mysteries are better left unsolved", there is a wide shot after he says this and every plate and glass from the table has disappeared. Added -(THAT'S THE JOKE MORON!!)

Continuity: When Peter enters the cockpit and accidentally kills the pilots the cockpit looks small enough so that it could only fit Peter and the pilots in their seats. However, when he turns around to leave the cockpit looks big enough to fit an entire group of people.

Continuity: When Death is talking about how he wanted to be a wood nymph, he has no pillows, but in the next shot, he has a blue pillow.

Continuity: When Karen Black is first shown, her blue uniform is sleeveless, showing her white shirtsleeves. After a cut to the "Dawson's Creek" kids, Peter says "It was a movie in the seventies," and Black's outfit has sleeves. Later, when she is helping people off the plane, her uniform once again is sleeveless.
