The Kiss Seen Around the World - S3-E8
Continuity mistake: When Stewie has kidnapped that bully he holds a weapon in front of the bully's face. When Lois comes in he puts it down, but in a full shot of the room it has disappeared. (00:19:30)
Continuity mistake: When Meg is waiting for Lois outside the hooters, she has a watch on her wrist. When she is talking with Lois, it just disappears after a couple of shots and we don't see it again. (00:11:10)
Chitty Chitty Death Bang - S1-E3
Continuity mistake: During the scene where Peter is taking Meg away from the cult group, in some shots he is wearing a watch and in others, he isn't. (00:18:40)
Continuity mistake: When Brian says "You can't just ignore these years", the front cover of his magazine is different from how it was in previous shots. (00:14:55)
Continuity mistake: When Lois is showing Stewie the tape in the car, the way she is holding it changes between shots. (00:07:30)
Continuity mistake: When Peter is improvising in the bank, the bag of money disappears in one shot. (00:17:30)
Continuity mistake: When Lois turns on her parents' bedside lamp, it only casts a small beam of light onto the floor, but later in that scene, the same beam of light is much bigger. (00:06:15)
Plot hole: Brian bets Stewie about being at high school for a week. However, this was before Peter's stroke, and before the fire at McBurgertown. It would take at least a few weeks for McBurgertown was rebuilt, then Peter had his stroke, and then Lois tells Chris Peter's stroke was 3 months ago. After this scene, Stewie tells Brian he has lost the bet. However, the bet would only last one week.
And Then There Were Fewer - S9-E1
Continuity mistake: When Muriel Goldman dies, everyone gathers up around her. When that happens, you can see Tom Tacker and Meg in the background, although they both disappeared a few scenes earlier. And than when everyone gathers downstairs, they do a body count and discover Tom and Meg are missing and only then are they found.
Continuity mistake: When Stewie pushes Brian down the stairs, in the background at the moment he pushes him that the stairs are visible behind Stewie as well.
Blue Harvest - S6-E1
Continuity mistake: After Vader (Stewie) kills Obi-Wan, Luke yells out and then the shot shows storm troopers firing at him with Vader in the background. Vader's lightsaber is blue, when it should be red. It is red in the previous and next shots. (00:34:00)
He's Too Sexy for His Fat - S2-E17
Continuity mistake: Just before the pest control team leaves for the Griffins', we see the black team member holding a shotgun in his hand. After showing Logan in shot, it returns to the black member and he's now holding what looks to be an MP5 machine gun. In the following shot as he starts to slide down the pole, the gun is once again a shotgun.
The Father, The Son, and The Holy Fonz - S4-E18
Continuity mistake: When Francis arrives, he changes from standing on the threshold to standing inside the house, even though he could not have moved between shots. (00:01:30)
Continuity mistake: When Meg is looking through her magazine in one shot there are just some adverts, but in the next shot there is a full page picture of someone. (00:01:20)
Other mistake: Peter goes back in time and sees Lois at age 18. Death says everyone will see Peter as being 18 too. Problem: Lois and Peter aren't the same age. In later episodes, Lois reveals she's 2 years older than Peter so Peter should be 16 when he meets Lois.
And Then There Were Fewer - S9-E1
Continuity mistake: Derek and Jillian are standing beside Consuela who is holding a tray with 5 glasses of wine. A split second later, when Derek gets 2 off the tray, the tray is left empty.
Continuity mistake: The interior of the Griffins' bathroom changes color (from yellow to blue), when Chris first talks to his pimple.
And Then There Were Fewer - S9-E1
Continuity mistake: When Derek Wilcox is killed and on the ground, he is on his front with his head turned. He got hit above his right eye and blood is coming from underneath him, but after everyone else arrives outside, he is on his back with the wound above his left eye and blood is all over his face.
I Never Met the Dead Man - S1-E2

Continuity mistake: During the scene where Joe is putting his trophies on the shelf, the size of the shelf in relation to the trophies changes. (00:07:15)
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.
