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: When we first see the merry-go-round that Peter and William Shatner ride on, there are four bikes on it, but in the next shot, there are three bikes. (00:19:15)

From Method to Madness - S3-E18
Continuity mistake: When we first see the sign outside the Quahog institute of performing arts, it has a cartoon take on the comedy and tragedy masks in the corners. In the left hand corner is a black mask with big ears and a smile and on the right is a white mask with a frown. Later on, the black mask has the frown and the white mask has the big ears and smile and the 3rd time you see the sign it has changed back again.
To Live and Die in Dixie - S3-E12
Continuity mistake: When Peter and Brian are escaping from the locals in their car, they go over a ridge. They freeze in midair and a voice says "those Griffin boys..." and the screen goes black. Then, in the next shot, the whole landscape is different. Even though the angle of the shot is different, that doesn't account for the disappearance of Chris and Sam or the colour-change of the sky. (00:14:40)
Continuity mistake: After Conway Twitty finishes his song, the scene cuts back to Perter and his family at the kitchen table. Take notice that Lois is sitting next to the back door, and Brian is sitting next to the kitchen sink and window. Keep an eye on that kitchen sink, window and door, because it will be replaced by a yellow wall with the telephone now being closer to Lois. Later as Lois, Brian and Peter are discussing OJ Simpson, the sink, widow and door return.
Continuity mistake: When we first see the English family at the airport, the girl in red is carrying a blue pack, but in the next shot, she is carrying a doll. (00:05:30)

Chitty Chitty Death Bang - S1-E3
Continuity mistake: When Stewie comes in when the Griffin family is talking about Cheesy Charlies, his head and body are way out of proportion. He is right next to the rug where the family is sitting, yet he is about twice his usual size. (00:01:50)
Continuity mistake: As Brian is saying "OK, you know what, fine, you are a genius", the glass of water disappears. (00:05:55)
