Continuity mistake: Peter and Luke Perry go into Peter's house, and sit down. The door is open when they sit down. In the following close-up of Luke Perry, the door is closed, with no evidence of anyone, or anything, closing it.
Continuity mistake: During the scene where Chris walks into a hardware store, the antennae on the control on the back of his head change from straight to curled to straight again.
Suggested correction: I watched the hardware store scene carefully but I didn't see any difference on the format of the antenna on Chris' head. It's always stay curled in the whole scene.
Continuity mistake: Stewie takes the card from the predictor machine in his left hand but on close up it's in his right hand. (00:04:30)
Continuity mistake: The length of the antennae on the remote control on the back of Chris's head constantly changes between shots.
Continuity mistake: When Stewie is just about to fly into the fan in the Griffin's living room, having just attached the antennae to Chris, a green balloon appears on his back with the other three balloons.
Continuity mistake: Stewie floats over to Chris sleeping on the couch. Next shot shows Stewie getting tangled in the ceiling fan although there wasn't ever one in the living room.
