Continuity mistake: Stewie tries to get his mind control device back from the kitchen. The cupboard door is open when he falls. In the very next shot, Lois turns the light on in the kitchen, and we see the door has closed without anyone touching it. It is open again after that. (00:09:50)
Continuity mistake: When Peter is testifying in court, the microphone on the witness stand disappears in the shots from the judge's point of view. (00:18:43)
