Brian Wallows and Peter's Swallows - S3-E17
Continuity mistake: After Pearl dies, Brian rubs her cheek, but in the next shot, his hands (paws) are nowhere near her cheek. (00:20:35)
From Method to Madness - S3-E18
Continuity mistake: When we first see Stewie at drama class, there is a girl with pigtails behind Olivia, but when we next see Olivia, there is a black boy behind her.
Brian Wallows and Peter's Swallows - S3-E17
Continuity mistake: When we first see Brian at the Laser Rock Show, he is sitting next to a white shirted guy, but in the next shot, he is next to a blue shirted guy. (00:04:25)
Ready, Willing, and Disabled - S3-E15
Continuity mistake: When Peter is complaining to Brian about Joe doing the cereal ad, the position of the remote changes between shots. (00:14:15)
Continuity mistake: When Lois is first using the slot machine, the symbols differ between shots. (00:11:00)
Continuity mistake: Pay attention to the items behind the police auctioneer. In the first couple of shots we see a statue of a knight on a horse to the left of the auctioneer. When the camera cuts to Peter, and then cuts back, the statue is gone. The statue is then back in the next shot. (00:03:20)
Plot hole: As evidenced by the big bar room shootout, even if they couldn't die in this episode, wounds would still show up on your body (if shot with a gun, there would still be a hole). So, when Peter jumped off the building, when he hit the ground he should have been reduced to a fleshy puddle, even if he weren't dead.
The Kiss Seen Around the World - S3-E8
Continuity mistake: At school, when Neil is wearing the shirt that shows him and Meg, himself on the shirt has black hair at first. After Meg yells at him, he has orange hair on the shirt.
Chitty Chitty Death Bang - S1-E3
Continuity mistake: When Stewie is writing in his journal, in a far shot there is a yellow space ring on his bed spread, but in a close shot there is half a green planet. (00:03:50)

Continuity mistake: When Chris is sitting on the floor because Peter has taken the couch outside, his position in relation to the rug changes. (00:02:10)
Mr. Griffin Goes to Washington - S3-E3
Continuity mistake: When Peter goes to Mr. Weed's office for skipping work to go to a baseball game, he has a piece of paper in his right hand. When the shot changes, however, the paper is in his left hand.
Continuity mistake: When Stewie is just about to fly into the fan in the Griffin's living room, having just attached the antennae to Chris, a green balloon appears on his back with the other three balloons.
Continuity mistake: When Chris is sitting on his bed talking to Doug, the squares on his quilt pattern get smaller. (00:15:05)
Continuity mistake: When Stewie has been picked up by Lois and is being kissed by her, Brian freaks out. When you first see Stewie and Lois, Stewie's hands are on her shirt, next shot, they're on her arms. (00:19:40)
From Method to Madness - S3-E18
Continuity mistake: When the Griffins are dining with the nudists, the leaves on the corn in the middle of the table change colour. (00:04:20)

Continuity mistake: On Peter's letter to MacGuyver, the return address is '725 Spooner St.', but in other episodes, Peter lives at 31 Spooner St. (00:17:51)
Continuity mistake: When Gene Simmons points the microphone at Lois, she is surrounded by people with Kiss make-up on. In the next shot, when she says "Is that it?", she is surrounded by a different group of people, one of whom is not wearing make-up. (00:12:40)
A Very Special Family Guy Freakin' Christmas - S3-E16
Other mistake: When Peter runs over the manger with his car the camel flies towards the left out of shot, but when it falls on Peter it is falling straight down as if it was shot upward.
Continuity mistake: When the guys are all playing cards, Peter has a low amount of blue chips. In all the different shots, Peter goes from having no chips to having a lot. The pile is low in the above shots and high when it is close up on Peter.
Continuity mistake: When Peter comes home from his fishing trip he leaves mud prints all over the floor. Even Lois points it out, but after he goes through his two flashbacks, the mud is all gone. (00:03:15)
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.
