Continuity mistake: When Stewie is in his room talking to Rupert and himself out loud about Janet we see that Rupert is on the left side of Stewie's pillow. When the camera pans over to Brian who overhears Stewie's musings, after Brian makes fun of Stewie the camera pans back and Rupert is gone. There is also a quick tete-a-tete on the color of Janet's eyes and the final shot is on Stewie and his crib and yet no Rupert to be found. (00:07:20)Tobin OReilly
Continuity mistake: During the end of Peter's "revised" version of "The King and I" right after the scene where Brian and Peter kung-fu fight, the scene transitions to the next scene where a bunch of girls with bikinis on are surrounding Peter. During the transition, a girl appears out of nowhere. She is blonde and is leaning on Peter. (00:19:10)csteel310
Continuity mistake: When Simon is working with Stewie in his "The Life Cycle" exercise, there are three children behind him: a redhead with freckles, a blonde with glasses, and another blonde. However, after Simon turns around and says, "Any comments?", there is a wide pan of the kids in the class, and the three kids have completely disappeared.
Plot hole: If the groom didn't know who Lois was but had a picture of her, how could he have known that she was at the wedding so he could place the bomb in the blue sedan? If he had put the bomb in their car while they were still at home, they both would have been blown up. So this means he placed the bomb in the car at the wedding. He didn't know however that Lois was there until the end, where he caught up with them and told them not to start the car. Had he known earlier, he wouldn't have been arguing with his bride about the hit occurring during their honeymoon. (00:20:05 - 00:21:35)
Plot hole: Brian bets Stewie about being at high school for a week. However, this was before Peter's stroke, and before the fire at McBurgertown. It would take at least a few weeks for McBurgertown was rebuilt, then Peter had his stroke, and then Lois tells Chris Peter's stroke was 3 months ago. After this scene, Stewie tells Brian he has lost the bet. However, the bet would only last one week.
