Other mistake: It makes no sense that Brian ever drives a car. His feet don't even touch the pedals! Hes always sitting like a normal person does when they drive.
Other mistake: After the scene of the family watching Philadelphia at the movie theatre, Peter promises Lois that not a drop of alcohol is going to touch his lips. In this shot, Peter's buttons are on the left side of his shirt instead of the right like they should be. (00:03:39)
Other mistake: When Peter and the gang are watching TV drinking beers, the TV doesn't have any cables on the back. So how has it got power or a TV signal? This mistake was later referenced in "Back to the Pilot." (00:04:16)
Other mistake: After Stewie gets his toy back from the cupboard, Lois and Peter walk into the kitchen. Lois asks Peter, "Since when are you so concerned about our food budget?", and in the next shot of Peter, the buttons on his shirt are missing; then they reappear in his next close-up. (00:10:01)
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)
I Never Met the Dead Man - S1-E2
Other mistake: After Meg is pulled over by the police officer, in the situating shot of Peter driving Meg home, it appears that Lois is sitting next to him in the passenger seat, but it's really Meg. (00:05:30)
I Never Met the Dead Man - S1-E2
Other mistake: When the freezing rainstorm first starts, it cuts back to Peter and William Shatner. In this shot, a woman in the background is running towards the right side of the screen, then disappears mid-shot without leaving the frame. (00:19:29)
Other mistake: When Lois is saying that she'll make a nice romantic dinner, Chris's picture on the wall not only looks completely different, but he's wearing glasses. (00:08:00)
Other mistake: When Chris is telling Peter that he is out of the scouts, pink can be seen through his earring, even though his earring is in front of his blonde hair, not his skin. (00:06:30)
Other mistake: When the family is driving to New York, another red car passes in front of them from the right where there is no road. (00:09:35)
Suggested correction: Usually this would be right, but it's evident by their positioning that Peter is actually driving his car right in the middle of the road on the dotted line and not staying in one lane. This is why the truck passes on the left to get in front and then the car on the right, both also getting centered on the dotted line.
Other mistake: Throughout many episodes, it's discovered that anybody that touches Death immediately dies. When Stewie learns that Death has come for Peter, he immediately touches his finger to lead him inside but manages to live.
Other mistake: In the scene where Einstein is stealing Smith's theory, when Einstein pulls the metal bars down, they should land on Smith's head, but Smith inexplicably moves forward and the bars land on his back.
Other mistake: In the flashback to Brian and Peter playing checkers, Brian's piece is not on the back row when he says "king me."
A Picture Is Worth 1,000 Bucks - S2-E11
Other mistake: Brian says he met Antonio Monatti when he was with Andy Warhol in the '70s. This is an impossibility. Only several episodes earlier (in episode Brian in Love), we find out that Brian is 7 years old.
Fifteen Minutes of Shame - S2-E12
Other mistake: Right at the end, when Peter takes out the Bible, the front cover is on the wrong side, i.e the back.
Other mistake: After Brian says Chris is tweaked and Chris says maybe the toad is Meg's, the bubbles in the aquarium stop moving. (00:03:35)
Other mistake: When Peter is dancing to his musical number on top of the table, his head continually shrinks until the end of the shot, where his head is around a third of what it was originally. (00:11:00)
Other mistake: While Lois is kneeling at the entrance of the playground with Stewie, a woman is walking by carrying a baby. The playground gate entrance is casting a long shadow; however, Lois, Stewie, and the woman are not casting shadows in the same way. (00:03:35)
Other mistake: This mistake appears to only be in the digital version of the episode on Hulu and Disney+. After Stewie fires the net gun at the other kid in the Duck Duck Goose game and says he's still it, we get our first real look at Janet as she giggles at Stewie. For a few frames as it zooms in on her, the top of her head is cut off and blinks out of existence. (00:05:55)
Other mistake: After the Kentucky cut away with Peter, we're back on the plane. He sits down and is surrounded by the exact same other characters from the last plane we saw him on: the pink lady sitting next to him and the man in the green suit sitting behind him. This is after at least a day or two in the episode, and Peter is flying all over the world on different planes as a freeloader with his wife's new job. It's next to impossible that he'd be sitting next to the same lady and in front of the same man again. (00:09:30 - 00:15:10)
