Continuity mistake: Stewie forces Lois to breastfeed him, and she undoes her shirt. As Brian and Lois argue about who is going to test her milk, Cleveland barges in and is shot. When Lois jumps up, her shirt is buttoned again, with no time for her to do it.
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.
Other mistake: During the Vagina Monologues show, the pair of legs casts a shadow but the microphone stand doesn't. (00:00:45)
I Never Met the Dead Man - S1-E2
Continuity mistake: When Lois and Peter are in bed prior to the Raisin Bran spoof, in one frame Peter is not wearing glasses, the next close-up he is, and in the next frame he is again without glasses. (00:14:50)
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.
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.
Other mistake: In season 4 episode 7, 'Brian the Bachelor'. Cleveland is sitting in a chair in a waiting room and is getting really nervous. Peter tries to help him by tying him to a chair and when that doesn't work, he takes off all of their clothes. Peter ties Cleveland's hands to the arms of the chair and then takes Cleveland's clothes off. He couldn't have taken the shirt off while Cleveland's hands were tied to something without untying him or ripping the shirt, which he didn't do.
The Cleveland-Loretta Quagmire - S4-E5
Continuity mistake: After Quagmire jumps through the window, the glass shards on the ground disappear. (00:18:30)
Audio problem: When Peter introduces the pope to his friends at work, and he is saying "Remember when we got that stripper for Charlie and it turned out to be his son? I think this is gonna top it" or something along those lines), Peter's mouth very obviously does not sync up with the words being said.
Continuity mistake: When we first see the English guy in his car, his crates of goods are stacked askew in the back seat. After Peter's crew shoot the car several times and the car is half-wrecked, the boxes are suddenly neatly packed into the seats. Moments later, we see the boxes piled randomly again. This change happens a couple more times before the scene is over.

Continuity mistake: In the scene where Al Cowlings and his "trusty white bronco" help the Griffins escape, his white horse changes color to light brown during the passing view then changes back to white in the following overhead view.
From Method to Madness - S3-E18
Revealing mistake: After the fight between Stewie and Olivia at the concert hall (followed by their breakup), Simon tells Stewie that the act without Olivia is "over" as he turns to walk off the screen. However, before Simon is even partially out of the shot, he completely disappears. (00:18:45)
He's Too Sexy for His Fat - S2-E17
Continuity mistake: In the scene where Stewie is eating chocolate cake, he shoves his head in it and covers himself in cake. However when Peter walks in after having liposuction, all the cake has disappeared and Stewie is now completely clean. The bowl of grapes on the table is also gone. (00:11:40)
I Never Met the Dead Man - S1-E2
Continuity mistake: The seating arrangement of the students preparing to throw paper wads at Meg during the Wonder Years parody changes depending on the camera angle. (00:09:50)
Continuity mistake: When Stewie is trying to get a drink from Brian, there are two alcohol bottles on top of the table. But one is gone for two shots, then comes back. Also the bottles change from closer to father.
Continuity mistake: In the first shot of the flashback showing the family watching "Philadelphia," Peter's eyes are about twice as big as they normally are due to the Irish coffee, but are instantly back to normal in the next shot.
Family Guy Viewer Mail #1 - S3-E21
Continuity mistake: When Lois is saying "We each seem to have acquired superpowers.", her size in relation to the chair in front of her changes between shots.
Continuity mistake: When Peter is calling for people to fight Lois, he is standing next to a sign that says "Fight the ass kicking housewife" and has metal rings at the top. When it moves to a closer shot, a hyphen has appeared between "ass" and "kicking". Then, after the space where the commercial break would have been, the sign now says "$10.00" and there are no metal rings. Finally, in the next shot, the sign says "Fight the..." and has metal rings on top. (00:06:55)
Character mistake: When all the wives are in the van Lois calls Bonnie "Debbie".
Stewie, Chris & Brian's Excellent Adventure - S13-E7
Factual error: The Titanic set sail from Southampton, not from London. (00:11:30)
Answer: Lacey Chabert was the actress who originally voiced Meg in early episodes. She left of her own accord due to being in school and other acting work; Seth MacFarlane has stated there was no tension with her leaving, but it makes for a handy joke for the show.
