Character mistake: After Stewie and Brian go to tell the past versions of themselves not to tell 1999 Brian about 9/11, Stewie then finds out that Brian then told 1999 Brian to write the Harry Potter novels. This would have been impossible because the first Harry Potter novel was published in 1997, 2 years before the time period Stewie and Brian arrive in. (00:16:35)
Continuity mistake: After Mayor West enjoys eating the taffy, when it cuts to the Griffin family standing on their lawn, the post-mounted mailbox is placed on the right side of the front door's walkway, but then it switches to the left side of the walkway.
Other mistake: When the family gets to the top of the mountain Brian goes left off-screen to pee. Lois says "we proved we aren't second best." Wideshot shows the Fishmans sitting there. They would've all seen them when they got there, yet they are shocked when Ross says "Well look who finally got here." And they are only inches apart.
Continuity mistake: After the LASIK surgery Lois has bandages covering her eyes, and the pairs of crisscrossed tape switch their over-under positions within the same shot.
Continuity mistake: When Meg, as X-Men's Quicksilver, starts to spite her whole family at the speed of light at the beginning of the episode - just after Chris sneezed in front of everybody - she initially throws his hat away from him, but in the next shot when she gets back on her seat, Chris' hat returns resting to his head.
Baby, You Knock Me Out - S9-E5
Continuity mistake: Peter sets his globe on the table beside the box it came in and walks over to Joe and hugs him. Next shot shows the globe back in the box on the couch even though you see the edge of the box the whole time.
Space Cadet - S11-E9
Revealing mistake: When Chris is giving them a tour of the shuttle, they are standing up normal. When they take off, they are still standing straight up. The shuttle goes straight up. You would be on your back at take off. They would never be able to stand straight up.
Continuity mistake: When Joe eats ice-cream on a mini batting helmet during the football match, some ice-cream is visible fallen on the ground just before the drink seller comes. In the next shot it disappears. (00:02:40 - 00:03:01)

Peter's holding this book in his hands when he asks Consuela what happened, and just as Consuela tells him about her nephew, we see another blue book on the desk beside Peter. There should be only one blue book - the one in Peter's hands. (00:20:40)
And Then There Were Fewer - S9-E1
Continuity mistake: When everyone enters the secret room there's a tall lamp (which is turned on) on the desk, but after Peter finds the book, just as he asks Bonnie about being punched in the throat, the lamp has vanished in this shot. (00:20:15)
And Then There Were Fewer - S9-E1
Continuity mistake: The interior layout of the dining room is visible in many shots, specifically the wall and windows behind the arm chair at the head of the table. After Stephanie is murdered, when Mort shouts to run for their lives, the crowd exits the dining room and they turn right, then everyone runs for the double front doors, opposite the staircase. This means the windows behind the arm chair at the head of the table are at the back of the house, but later when they capture Tom behind that chair, the shot moves backwards through the window and it's now at the front of the house, beside the double front doors. (00:10:50 - 00:37:30)
And Then There Were Fewer - S9-E1
Continuity mistake: When Muriel disappears after she's been accused, everybody rushes back up the secret passageway stairs to find her, and in the first shot facing the group there's a large green desk pad on the desk, but in the next shot that desk pad has vanished (and it reappears when they split into groups). (00:21:55)
And Then There Were Fewer - S9-E1
Continuity mistake: When Joe concludes that Stephanie was in the wrong place at the wrong time, the dining room table is still set with plates, wine glasses, etc, but then Joe tells everyone to look around for more clues, and in the next overhead shot as they all exit the dining room the table is bare. (00:15:55)
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.
