Corrected entry: In the scene where Brian and Lois are talking in the bedroom, you can see that they both sleep in two separate beds. However, in a different scene when Lois is riding on top of Peter in the bedroom, you can see there is only one double bed inside the room.
Corrected entry: In the scene where Peter gets Chris a bullfrog you see him walk through the door on the right but when Peter tries to get the bullfrog out the window the door is replaced by the window.
Correction: The door does not move, we are just viewing the scene from a different angle.
Corrected entry: When Stewie's chatting up 'Misti', the equation he writes on his napkin changes between shots. (00:11:40)
Chitty Chitty Death Bang - S1-E3
Corrected entry: As Peter is saying "Today, you become the man of the house because when we get home, you're mother is going to kill me", Peter and Chris walk past the same four arcade games twice. (00:07:35)
Brian: Portrait of a Dog - S1-E7
Corrected entry: When Brian is putting in his eyedrops, notice his buckle on his collar. In the next shot, we see Brian's reflection in the mirror, but the buckle is not flipped. (00:05:45)
Corrected entry: When The Griffins leave to New York in their car the order in the back is Chris, Stewie then Meg, but in the next shot it's Meg, Stewie then Chris. (00:07:55)
Corrected entry: When Peter goes back in time to when he was eighteen, Brian points out Lois and refers to her as "eighteen-year-old" Lois. In the episode "Let's Go to the Hop", in the second season, Lois mentioned that she is two years younger than Peter. She would actually be sixteen when he is eighteen.
Correction: Brian's just gone back in time and is now seeing the woman of his dreams as a hot teenager. He made a mistake, that's all.
The Thin White Line (1) - S3-E1
Corrected entry: In the scene where Brian and Joe bust the "Sunday school drug ring," the two get in a brawl with a group of drug-running midgets. Joe throws his nightstick at one drug-runner, punches a second, but kicks the third drug-runner, despite the fact that Joe is a paraplegic.
Correction: Already submitted and corrected. He swings his chair around so violently his legs come flying up due to the centrifugal force. He doesn't move them himself.
Corrected entry: The sheet of toilet paper change numbers when Lois tears them off to put on the seat (right before she sees Quagmire peeping on her). She tears off three sheets, but they change to four when she puts them on the seat. (This happens on both sides of the seat).
The Tan Aquatic with Steve Zissou - S5-E11
Corrected entry: When Peter and Kyle are talking in Kyle's bedroom (just before Peter beats Kyle up), Kyle mocks Peter by saying "My name's Peter Griffin! I'm a big fat dumb butt-face!", but Peter never introduced himself as 'Peter Griffin', he introduced himself as 'Chris Griffin's father'.
Corrected entry: Joe Swanson says he spent his tax return on a new State-of-the-art TV with surround sound but later in the episode we see this TV when the power goes, doesn't look very new or modern.
Correction: He's only allowed to own one television set?
Plus that could very well be state of the art, compared to no TV at all.
The Thin White Line (1) - S3-E1
Corrected entry: When the Griffins are driving Brian to rehab there's a front licence plate on the car, but it has no characters on it.
Correction: So? It's probably a white piece of plastic. Our truck has that too.
Corrected entry: When Peter has a flashback to his sixteenth birthday party there are only 12 or 13 candles on the cake. (00:16:20)
Stuck Together, Torn Apart - S3-E19
Corrected entry: This episode explains that Stewie's head became that weird shape from banging it on the roof. But in earlier episodes showing his birth, his head has always been that shape.
Correction: It's a cutaway scene. Most of these did not happen in the Family Guy "world" but meant as jokes for the story.
Corrected entry: When Quagmire calls 911, his hand actually dials '044'.
Correction: You never see Quagmire dial the phone, just his body stuck in the window.
Corrected entry: As Lois sprays the Oval Office with machine-gun fire, she hits all the Presidential portraits with bullets, but fixates on George W. Bush's, shredding it to pieces. A few scenes later, the GWB portrait is shown with just a few holes in it, hardly shredded.
Correction: As stated at the end of the episode it was only a simulation almost like a dream. Due to the programming of the simulation there could have been a flaw that caused the picture to fix itself.
Halloween on Spooner Street - S9-E4
Corrected entry: Meg goes to the party wearing a mask without her glasses on. When she's in the closet, her mask is off and she has her glasses on, even though she didn't wear them to the party. (00:06:50)
Correction: When Meg tells her mother she's dressed as a slutty cat, Meg is wearing her eyeglasses and pulls the cat mask down over her glasses, then she leaves the house. We see Meg is still wearing her glasses under her mask when Joe drives past her and her friends, right before they all enter the party.
Correction: Is it not possible that she may have had them in a pocket or somewhere and then put them on when she took the mask off?
Her costume had no pockets. It showed her leaving the house without her glasses.
But it did show her leaving with her glasses on.
Some people wear regular clothes under a costume in the event that it might have been cold. Rhode Island might be a bit cold at that time of year (I live in southern Canada and it can be very cold on Halloween) Maybe her glasses were in a pocket under the costume.
It seems like you didn't watch the scene before commenting and you're just guessing. She wasn't wearing normal clothes underneath and there were no pockets. The reason the mistake is incorrect is because, as stated, she is wearing them before she pulls her mask down and so she's wearing them under her mask when she leaves.
Correction: While married, Lois and Brian sleep in separate beds, which were specifically acquired for the purpose. When Lois is married to Peter, they share a bed. There's no telling how much time passes between shots and it's not that hard to move some furniture around.
