Continuity mistake: When Peter says he's gonna buy his family the biggest meal they've ever had, Stewie's eyes are drastically bigger than usual. (00:13:15)
Continuity mistake: When the Griffins are driving to Washington we see a faraway shot of the car driving from left to right. Peter and Lois are in the front and Chris is leaning back on the back seat. In the next shot, Chris is leaning forward against the back of Peter and Lois's seats. (00:19:30)
Continuity mistake: 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.
Other mistake: Right at the start when you get an aerial shot of the bowling alley, there is one that gets a strike. The machine sweeps them away, but the pins still remain. (00:00:05)
A Very Special Family Guy Freakin' Christmas - S3-E16
Continuity mistake: When Peter is driving, Quagmire is sitting beside him and Cleveland and Joe are in the back seat. Joe has brown hair and he's wearing a gray knit hat and a light coat with a gray fur collar. When Quagmire is sticking his body out of the car door and yelling "Whooooooa! Whoooooooa!", look at "Joe" in the back seat. Joe doesn't look like Joe in this shot. He's wearing a Santa hat and a brown coat just like Quagmire's, and a bit of his hair is also black like Quagmire's, instead of brown. (00:05:30)
Other mistake: When Stewie demands his device, he says, "Like a box of active grenades," and she gives it back. The pins weren't pulled, yet he runs and it explodes. (00:18:00)
Family Guy Viewer Mail #1 - S3-E21
Continuity mistake: When Lois picks up the fridge there is nothing stuck to the fridge but when she puts it down there is a note stuck to it. (00:09:40)
Jungle Love - S4-E13
Continuity mistake: In series 4 episode 13 Jungle Love: When the family are escaping the tribespeople, Chris is wearing the tribal clothing. When they jump in the plane there is a brief far-off shot of Chris wearing his usual cap and t-shirt. In a close up shot moments later, he is wearing the tribal gear again.
Continuity mistake: The English guy's car is full of crates when we first see it and when his roof is blown off but after Peter and a crewman have boarded, there are suddenly barrels in the car too.
Continuity mistake: The welfare cheque that Lois gets from the postal worker is addressed: 'Peter Griffin, 72 Spooner St, Quahog, RI' but the Griffins live at 31 Spooner St. every other time their address is mentioned. (00:14:26)
Continuity mistake: When Ulysses S. "Griffin" is chugging beer with Robert E. Lee, Ulysses wins. When he says "How's that Robert E. Lee," he puts the beer glass on his head. After Robert says, "Okay no more slaves, but we still don't have to read books," the glass is in Ulysses' hand. In the next shot it's on his head again. (00:10:05)
The Cleveland-Loretta Quagmire - S4-E5
Other mistake: When Peter is painting the Sistine chapel, he has green paint on his brush, even though the picture is entirely black and white. (00:03:50)
Chitty Chitty Death Bang - S1-E3
Continuity mistake: When Meg introduces Jennifer to Lois, she is, as usual, wearing her glasses. However, right when Jennifer says, "Bye Meg," Meg is seen in the shot, and her glasses have disappeared. Her glasses are back on in the next shot.
Continuity mistake: When Chris is saying "I'm not supposed to tell Mom cos she'll just bitch about it" there is a door behind Lois with a box next to it. In the next shot there is a smaller box next to that box which was not there before. (00:09:00)
Peter, Peter, Caviar Eater - S2-E1
Continuity mistake: In the scene where Lois goes down to the room where Peter is dancing, Peter is wearing blue pants. After he walks over to the door and greets her, he still has blue pants. The next shot of Lois and Peter dancing has him wearing his normal green pants, but after that it goes back to blue pants for the rest of the scene. (00:11:35)
Continuity mistake: 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. (00:03:35)
The Father, The Son, and The Holy Fonz - S4-E18
Continuity mistake: When Stewie is in the sterile glass cage, Lois is changing his diaper with rubber gloves built into one of the panels (like Homer Simpson's in the opening credits). In previous and subsequent shots, however, the panel is solid glass, with no gloves. (Series 4: The Father, The Son, and The Holy Fonz).
Continuity mistake: When Tom Tucker is reporting about Peter saving Horace, his angle in relation to the bar changes. (00:19:00)
I Never Met the Dead Man - S1-E2
Continuity mistake: The family visits Peter in the hospital. In the long shot, there is nothing on Stewie's head. In the next close up, a band-aid appears on his head. (00:20:30)
Answer: Mort is Jewish, and Walt Disney was said to be antisemitic. So it would make sense in a Disney universe all the inhabitants would share his supposed beliefs.
