Yug Ylimaf - S11-E4
Continuity mistake: The damage to the bedroom wall changes from when they hit the wall to when they wake up. (00:05:30)
Yug Ylimaf - S11-E4
Continuity mistake: When Stewie and Brian are thrown into the wall the debris on the floor around them changes when they come to. (00:05:30)
Yug Ylimaf - S11-E4
Deliberate mistake: The time machine reverting causes everything in life to go backwards. However, although the characters' actions are reversed, their dialogue is always spoken forwards and not backwards. (00:08:00)
Yug Ylimaf - S11-E4
Other mistake: Everything goes backwards in time and goes that far back that Meg (who is voiced by Mila Kunis) goes back to being voiced by Lacey Chabert (who voiced Meg in season 1). However, when Lacey Chabert does her line to Stewie being in the Griffin house for the first time, it goes back to Mila Kunis when Stewie is "reborn". However, if everything was going backwards and Brian fixed everything to make it goes forwards again, then it still should have been Lacey Chabert voicing Meg, not Mila Kunis. (00:16:30 - 00:19:35)
Yug Ylimaf - S11-E4
Continuity mistake: When Stewie is born whilst time is reverting, Doctor Hartman says "It's a girl... with a penis and no vagina". Then after Brian restored the flow of time and Stewie is actually born, Doctor Hartman instead says "It's a boy". (00:18:25 - 00:19:55)
Yug Ylimaf - S11-E4
Factual error: Near the end when Stewie is being put back and out of Lois's womb, he has no umbilical cord attached to him.
Yug Ylimaf - S11-E4
Continuity mistake: In reversed time, we see Cleveland falling back to the inside of his house that had just been wrecked by Peter who launched himself with a cannon into it. The camera zooms in on Cleveland as he falls back to the inside of his house, only for Peter to suddenly be visible along with an additional piece of the roof taken away, after the area in which Peter would appear on and the roof-piece disappear at was off-camera for a few seconds.
Answer: Lacey Chabert was the actress who originally voiced Meg in early episodes. She left of her own accord due to being in school and other acting work; Seth MacFarlane has stated there was no tension with her leaving, but it makes for a handy joke for the show.
