Continuity mistake: When Peter is giving the team steriods, the syringe always goes back to the same place.
Continuity mistake: When Peter and the rest are at the bar and Quagmire is telling Peter that he looked through his garbage, Quagmire's mug tops up between shots.
Factual error: When Lois, Meg, and Chris go to the stage show on the West End, "theater" is spelled with the Americanism "-er" instead of the UK spelling "-re."
Continuity mistake: When Stewie is playing golf at the top of the stairs before attacking Brian, the layout of the upstairs floor changes quite radically between shots. First Stewie is playing golf with the stairway behind him. Then when Brian puts on the disguise and walks past, there's suddenly a wall behind Stewie. Brian walks off to the left and Stewie begins to chase him that way, but in the next shot Stewie is chasing Brian off to the right. In that same shot you can see that Stewie is running away from the stairs, but in the next shot, without changing direction, he pushes Brian down the stairs, which mysteriously have appeared in front of him.
Continuity mistake: During the scene where the Griffins have Tom Brady over for dinner, when we first see the establishing shot of everyone at the table, Chris is sitting with an empty chair between him and Tom. However, when he asks if he can call him Tom along with Lois and Meg, he is sitting right next to Tom, with no empty chair between the two.
Other mistake: When Stewie sneaks into his parents' room and attaches the breastfeeding pump to Lois, he places the cups too high on her chest for them to be on her nipples. You can see this, especially after he removes the cups.
Revealing mistake: When Peter leans down to get the basketball, a dot briefly appears on his shorts, then disappears almost immediately.
Continuity mistake: When Stewie has chicken pox the red marks on his face change position many times between shots. A noticeable one is just as he is saying "No, damn you, I've got to finish what I started".
Continuity mistake: When Stewie and Bertram are parachuting down to Earth after the air strike, their parachutes get much closer to each other between shots. This occurs just before they start slapping each other.
Continuity mistake: Brian and Stewie see Meg enter Mayor West's motel room. She's wearing a purple dress. They follow them to a restaurant and Meg has her regular hat and outfit on.
Audio problem: In the flashback of Handful of Peter singing about the Indian chief, the musical notes Peter and Lois play continue to change pitch after they take their hands off their instruments' frets, which should default back to the open string notes.
Peterotica - S4-E24
Continuity mistake: After the Quahog Creek clip is over, they show a picture of the house. In the background there is a tall silver building that wasn't there the last time they showed a shot of the house. (00:17:45)
Peterotica - S4-E24
Continuity mistake: When Peter is reading Lois his erotica in bed, the size of his paper changes just after he says "his really cool spaceship".
You May Now Kiss The...Uh...Guy Who Receives - S4-E25
Continuity mistake: When Peter drives his car in the field it is perfectly visible, but in the next couple of shots the car's gone, and so are the tire tracks.
You May Now Kiss The...Uh...Guy Who Receives - S4-E25
Other mistake: When Peter is eating the Brownie, it stays the same with no bites.
Petergeist - S4-E26
Continuity mistake: The table with the TV on in Peter and Lois' room is just a small table at the beginning of the episode when Stewie talks to the poltergeist. But as they speak to Stewie in the TV it's on a high up chest of drawers. (00:08:00 - 00:12:00)
Petergeist - S4-E26
Other mistake: The Griffins' house disappears when they flee, but when they go to Quagmire's house after, you can see their house when they are at the front door. Quagmire's house is on the right of theirs and the angle of the shot is to the left so it's definitely their house, not Quagmire's other neighbours on his right. (00:16:36)
Petergeist - S4-E26
Continuity mistake: Lois slaps the skull out of Peter's hand and it lands on top of the dirt pile. They both turn around to look at the house and the skull is nowhere in sight.
Petergeist - S4-E26
Continuity mistake: The filing cabinet that was beside the TV moves to the corner beside the desk.
Petergeist - S4-E26
Continuity mistake: When the spirits first come out of the TV, notice the wall beside the TV. There's nothing there. Brian says who's here? Next shot shows a filing cabinet with a pink blanket on top.
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.
