Continuity: 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.

Continuity: In the scene where the family are singing an African song, they all point their arms up to the ceiling yet in the next shot, Lois's arms are imediatly cupped and pointed downwards- you don't see her moving her arms to that position.

Continuity: When Peter is pretending to be a man-eating tree, there is more of a shadow on the tree in the first shot than in the shot right after he spits out 'Dan Rather'.

Continuity: When Chris tells Meg not to rake the two leaves because they are his friends, one leaf is brown and the other is yellow. After Meg picks them up and crushes them, they're both brown.

Continuity: When the family is in traffic jam there's a shot from the front of the car, and in the next shot from the backseat of car, Peter's face (glasses and part of nose) is reflected in the rear view mirror. However, there's no rear view mirror in the first front shot or shots following backseat shot.

Other: When Lois knocks out the karate master, if you look in the stands there is a guy without a nose.
