Other mistake: When Peter tells Brian that "James Woods is being taken care of by top men" they show a philips head screw being hammered into the wooden crate in the warehouse. (00:20:15)
Continuity mistake: The buttons on Peter's white shirt switch between the left side and right side, between shots, such as when he tries to play frisbee with James, or when Peter is late for dinner with James.
Factual error: In the very beginning of Perfect Castaway, when Peter is talking to his workers and telling them he's going to have to "put them down", he pulls out a shotgun and four shells. He puts two shells in each barrel, but then continues to shoot 5 times when they jump in the water. First of all the shotgun is a double-barreled, break action type shotgun, so Peter should only have been able to put two shells in it. Second of all, even if he could put two shells in each barrel, he would only be able to fire it four times.
Continuity mistake: In the episode where Brian and Lois get married, Lois confronts Brian after cheating with Peter back at the house. Stewie is playing with a SIMON SAYS game. Look at the SIMON SAYS when he is playing it (up close), after he is done (the close up shot ends), look at the colors again on the SIMON SAYS, they change.
Factual error: When Stewie is playing Simon Says, the sequence Stewie plays is different than the one that the Simon Says played. If he played it wrong, there should have been a sound from the Simon Says indicating that Stewie played it wrong.
Other mistake: Peter says I can't afford to keep you. He puts 4 bullets in the shotgun. He shoots a total of 5 times.
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.
Jungle Love - S4-E13
Other mistake: In the kitchen when Peter is playing with the paddle ball and then Brian confesses to giving Chris the idea about joining the Peace Corp, there is a picture frame on the wall behind Peter. In this is various pictures of the family including Brian. In this, Brian is as a yellow dog despite being white in the series, and even in the scene depicted.
Continuity mistake: Osama bin Laden's dialysis machine disappears after Stewie knocks him down. (00:02:30)
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)
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.
