Corrected entry: In the flashback scene where Peter meets Lois' father, Peter openly farts in anxiety. However, it was discovered in the previous season, when Peter gets his breast examined, that Peter had gas for the first time when he was 30. In this season, it is noted that Peter and Lois have been married for 17 years, and that Peter is 42. That would make Peter at most 25 when he first meets his father-in-law to be, 5 years before he first experienced passing gas.
Corrected entry: Lois refers to Gene Simmons by the name Chaim Witz, and they both say they knew each other and had sex together before Gene became famous. But the name "Chaim Witz" was the name Gene used in Israel as a child. According to his autobiography, when he came to New York as an eight-year-old, his name was changed to Gene Klein, and he never used the name "Chaim" in the US. Lois could not have known him when he went by the name Chaim Witz, and could certainly not have had sex with him at the time.
Corrected entry: A mistake in the subtitles: As Stewie yells, 'I've got blisters on me fingers.' after singing 'My big old fat ass baby', the subtitles read: "Imitates John Lennon." It is widely argued, but McCartney and Starr claim that it was Starr who said that, after a particularly vigorous rehearsal for Beatles song, 'Helter Skelter'.
Corrected entry: When Brian is reading the diary of Nate Griffin, there is an entry about a new colt that farted on him while he was grooming. The entry refers to the colt as 'she' many times. A colt is a young male horse - they should use the term 'filly'.
Corrected entry: When Death and Peter get into a fight outside the pet store, Death controls his severed arm to poke Peter in the eyes. However, Peter is wearing glasses. His eyes could not have possibly been poked unless his glasses, for some reason, did not have lenses in them.
Corrected entry: When Peter pretends to play the keyboard in the toy store, a man takes exception to it. When the Griffins are back in the parking lot, the man has spray painted the word "Phony" on their station wagon. The man just met Peter two minutes earlier, how would he know which vehicle to spray paint? (00:01:20 - 00:02:15)
Corrected entry: Peter and Carter Pewterschmidt, Lois's father, are in a game of Texas hold 'em poker with Michal Eisner, Bill Gates and Ted Turner. After some betting, Carter shows his hand, as does Ted. The problem is that anyone who has ever seen Texas hold 'em knows that they are not playing correctly. Each player has two cards to themselves and five community cards. It might be minor, but why mention a specific game such as hold 'em then not follow the basic rules of the game?
Corrected entry: At the beginning of the episode, Chris gives Stewie a candy cane, which Stewie immediately begins sharpening with a knife, with the intent to stab Lois with it. But if Stewie had a knife the entire time, why didn't he just stab Lois with that?
