Continuity mistake: When the Grinch drops the sack, the sack lands next to him, but in the next shot, it is gone. (00:11:45)
Continuity mistake: When Peter is improvising in the bank, the bag of money disappears in one shot. (00:17:30)
Continuity mistake: When the policeman asks Lois to describe Peter, it shows a view through a scope of a rifle. However, when the shot changes and the cop says "I've got him", there is no scope on the rifle. (00:18:15)

Continuity mistake: Peter picks up the phone to call the Scout leaders and points his finger up in the air. In the side shot, it's just his finger extended up, but when it cuts to a closer angle, suddenly his thumb is extended outward as well. (00:07:00)
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 Brian is watching TV at first the remote is on the right hand side and there is an olive in his glass, but in the next shot the olive is gone and the remote in on the left hand side. (00:08:10)
Continuity mistake: In the car, Peter talks about how he shouldn't have had that prune smoothie. Suddenly their car has no rear window, and the ceiling of the car is completely different with lines going everywhere and extending back down over where the rear window used to be. (00:09:24)
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.
Continuity mistake: When Lois is first using the slot machine, the symbols differ between shots. (00:11:00)

Suddenly that chair that was empty now has an Native American in a grey suit sitting there. (00:15:44)

Continuity mistake: When the head Native American is saying he wishes he had a spiritual vision also, there is just his right hand man beside him and the Indian in the grey suit to his other side with nobody directly behind him. When the camera cuts to a wide angle from more of a distance, suddenly the fat Indian with the cigar appears behind him, then vanishes again in the next shot. (00:20:04)
Continuity mistake: On the couch, Lois tells Peter that maybe Chris is the one that should be earning that badge. As she does, Peter's arm is down at his side and her hand is resting on it. It then cuts to his reaction and suddenly his arm is out in front of him with no time between shots.
