Continuity mistake: After Peter tries to bribe the admission at the University, he, Lois, and Meg sit down on a waiting couch as Lois says she had friends who got shot at her old school. There is a painting of a yellow building on the wall above and behind them. It has 8 windows at the top. In the next shot, it just has 7 windows at the top. Also, the bushes and road are drawn a little differently with less road visible through the bottom bush. (00:02:08)
Deliberate mistake: At the start of the episode, the family is watching a show called "Sherry and the Anus." When Sherry opens the door and walks in, there is a Star Wars poster hanging above Anus' dresser. However, it doesn't resemble Star Wars at all. The font is all wrong, the lettering is the wrong colour, and the ship on the front is some generic-looking spy plane and nothing like a Star Wars fighter. This was obviously done to avoid any copyright issues, as this was before the Lucas partnership later on. (00:00:07)
Continuity mistake: At the end of the episode when Peter is meeting with Mayor West, there are military generals standing behind West. When it cuts to a close-up of him, suddenly the generals behind him disappear. (00:20:45)
Continuity mistake: After La Toya Jackson says the prayer in Mayor West's office, the military personnel that were behind Mayor West vanish in the next shot. (00:20:55)
Other mistake: When Peter sits down with Mayor West to discuss terms, West says, "Thank you all for coming." As he does, he tilts his head down and the bottom half of his nose disappears until he moves his head again. (00:20:38)
Continuity mistake: In the UN Cafeteria, Peter goes to sit down next to some other world leaders for lunch. Between shots, the size and shape of the food trays change, and also the Asian guy's tray vanishes altogether. (00:12:50)
Continuity mistake: When Chris tells Peter that some guy won't let him go to school, Peter turns so that his front doorway threshold is to his right. But then, when it cuts to the next shot with Peter asking "him and what army?", suddenly his back is to the doorway again. (00:14:07)
Continuity mistake: In the kitchen after Petoria is cut off from the world, the fridge is shown with two notes on the freezer door next to the handle with scribbled writing on them. After Stewie takes a dump in his newspaper diaper, it cuts to a different closer angle, and now the writing on the notes has vanished. Usually in animation, details being lost in a further out shot is normal; however, this is details lost in a closer angle. (00:17:42)
Continuity mistake: At the pool party with the other world leaders in Joe's pool, Achmed is cooking on the grill and Stewie is standing on a blue stool next to him. Moments later, in a closer shot of Achmed, the stool Stewie is on is suddenly brown with grey legs. (00:18:18 - 00:18:58)
Continuity mistake: In the Ulysses S. "Griffin" cutaway gag, just when Griffin and Lee go to start chugging their beer, the soldier behind Griffin suddenly goes from brown hair to blonde. The soldiers also get closer together between shots. (00:10:04)
Continuity mistake: After Robert E. Lee loses the drinking contest to Griffin, he sets his mug down and it is under half full. In the next shot, suddenly it's about three-quarters full. (00:10:08)
Continuity mistake: In the Can't Touch This parody song with Peter, he chains Joe to the back of the truck with a chain. Between shots, the handle of the door changes from grey to a silvery white, the chain itself changes from grey to black, and the panels under the chain and handle go from grey to a darker bluish-grey colour. (00:11:45)
Revealing mistake: After Peter's encounter with Mayor West, we have the family standing next to the sidewalk in their front yard. Lois walks up holding Stewie, and now you can see there is a perspective error in the animation as next to Lois the mailbox looks comically small, barely big enough to put a stapler in. (00:08:11)
Continuity mistake: When Peter walks in the front door with his tax refund, he does not shut the door after approaching the family on the couch. Yet moments later, when Peter goes to sit down, the door has shut all by itself. (00:02:34)
Continuity mistake: When Peter sits down at the desk in the IRS office, there is a pen and what appears to be a business card on the corner of the desk next to where he’s sitting. After Miss Stratford says she farted, it cuts to a frontal angle of Peter, and suddenly the pen and business card have disappeared. (00:03:07)
Continuity mistake: After the IRS visit, Peter is digging a hole in his back yard for a pool. His kids are standing around at the edge of the hole watching. When it cuts to a close-up of Stewie, he's suddenly standing much closer to the hole. (00:04:18)
Continuity mistake: Peter enters Adam West's office, and the words "Adam West Mayor" are on the door. Adam West then tackles Peter to the ground and starts punching him in the next shot. During that moment, part of the letters are still seen, and the "OR" at the end of "MAYOR" is noticeably much smaller, and the "R" is a different shape. (00:06:45)
Continuity mistake: In the cutaway gag after Peter says he thought about selling his body to science, there is his skeleton in a classroom hanging up. The teacher asks a girl to come up to it, and between shots, the stand his skeleton is hanging on moves much closer to the wall and corner of the room behind it. (00:01:03)
Continuity mistake: At the IRS, when Peter walks into Stratford's office there is no light switch beside the doorway, but a 3-gang rocker light switch appears in following shots. (00:03:02)
He's Too Sexy for His Fat - S2-E17
Continuity mistake: Once Peter comes home with hunky muscles, Lois starts pushing the kids out of the front door. Stewie is in a wagon beside the threshold of the door, and he turns his head to look at Lois next to him as she pushes Chris and Meg outside. In the next shot, suddenly Stewie is now directly in front of the door, with Lois in front of him, and his head has turned again. (00:15:50)






Answer: Lacey Chabert was the actress who originally voiced Meg in early episodes. She left of her own accord due to being in school and other acting work; Seth MacFarlane has stated there was no tension with her leaving, but it makes for a handy joke for the show.
