Continuity mistake: When Peter and the family reach the top of Mt Everest, it shows a long shot of them all by themselves. Cut to Lois talking - another family is suddenly sitting there, and the woman says "we beat you by one hour and 11 minutes." (00:14:00)
Continuity mistake: When Brian and Stewie arrive in Leonardo's atelier, we know that they are in Florence for two reasons: because of history and because we see Palazzo Vecchio (which is in Piazza della Signoria, in Florence) outside the window. Then, when Stewie and Bertram are fighting with Leonardo's flying machine, the city of Florence is wrongly represented as if it were Venice, with the sea, the lagoon, and the canals.
Revealing mistake: When Brian says "Our tickets were in the bags", half of his left hand is missing for a frame.
Revealing mistake: When Brian asks Peter how much money they're getting from welfare, his neck is drawn over his collar, making his head look like it's disconnected from his body.
Continuity mistake: In the episode "FOX-y Lady" (7-10) it was established that Quagmire was 61 years old. In this episode, Quagmire stated to Meg he was bullied in 1986 and a flashback shows that he was a teenager. So how could Quagmire have been bullied in 1986 as a teenager if he should have been in his 30's at this time? (00:12:15)
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: 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)
And Then There Were Fewer - S9-E1
Continuity mistake: When Mayor West panics, Peter shakes him and he falls against a shelf. The plate on the end of the shelf falls off and smashes on the floor. But when Brian points out the gun is there, it is now the middle plate that fell off and the plate on the end of the shelf is intact. (00:15:25)
And Then There Were Fewer - S9-E1
Continuity mistake: Just after Stephanie is killed, there is an outside shot of the manor, where the weather is normal. Just 20 seconds later when they run outside to try and escape, it is suddenly pouring down. (00:10:40)
And Then There Were Fewer - S9-E1
Character mistake: When driving to the manor, Lois wakes up and says "Peter, look" as if she knows they are there. She could have not been able to notice this since the trees are blocking all view of the manor. (00:03:00)
And Then There Were Fewer - S9-E1
Continuity mistake: There are several differences during the flashbacks and what actually happened. Such as when Muriel is killed Diane appears with everyone else, but in the flashback she appeared moments later. Second, when everyone appears in front of Derek's dead body there are two differences, Tom doesn't say "Dear God!" in the flashback and Diane appears 1 second later in the flashback. Third, Stephanie doesn't say "Did the cork hit me?" when she is shot in the flashback. Fourth, Priscilla isn't wearing a scarf in the flashback even though when it actually happened she was wearing a scarf. Fifth, when Derek says he is going up to the roof he is standing next to Peter and Lois, in the flashback he standing next to Lois and Jillian. Sixth, when Derek leaves the dining room to go to the balcony, no-one is standing next to the door, but in the flashback Diane and Doctor Hartman are standing right next too the door. Seven, when Muriel is killed she is in the middle of a hallway. But in the flashback, she is killed outside Tom Tucker's room.
He's Too Sexy for His Fat - S2-E17
Audio problem: When Peter is driving in the car, he can't stop admiring himself in the rear view mirror. He is talking while looking in the mirror, but you can see the corner of his mouth not moving. (00:20:58)
Continuity mistake: As Lois pats Brian, her elbow changes position. (00:16:45)
Continuity mistake: When OJ Simpson first meets Peter for their game of golf, both Peter and OJ have only four irons and a putter in their golf bags; however, when OJ tees off, he does so with a wood.
The Former Life of Brian - S6-E12
Plot hole: Brian has a 13-year-old son. Not possible since Brian has only lived 7 years.
Other mistake: The guys all go water skiing, towing the boat behind Peter's car. After Quagmire gets his penis bitten off the scene cuts to the hospital parking lot. Quagmire's car is parked next to Peter's. There would be no reason to go home and get his car instead of going directly to the hospital. (00:07:15)
Plot hole: When Stewie and Brian are at the diner Stewie says he negotiated a deal with the mob by telling them he convinced Mort to give him his flash drive with the info to put the mobsters in prison. When they actually meet, Stewie tells the mob guys the flash drive is "his" and that he bought the coverage. Then he says his address is on the drive so they can mail it back to him. The mob guys didn't realise Stewie lied about whose flash drive it really was. (00:15:40 - 00:19:00)
Stewie, Chris & Brian's Excellent Adventure - S13-E7
Factual error: In the episode, the Titanic is shown to have sunk the same day it left England. The actual Titanic left England on April 10th and didn't sink until the night of April 14th, almost four days later. (00:11:40 - 00:15:30)
And Then There Were Fewer - S9-E1
Other mistake: When everyone is leaving the mansion after Stephanie was killed, 3 mistakes happen at the same time: Dr. Hartman came alone, but there is a person sitting in the front seat next to him. Derek is in the car he and Jillian came in when they got here, but he is alone. And Carl was getting into Herbert's Ice Cream Truck, which was in front of his own truck.
Factual error: In the bit when Brian and Stewie are in Poland, the sign they are looking at should say Warszawa, not Warsaw.
Chosen answer: It's a real song called "Elvira". Originally by Dallas Fraizer in '66, however, this version seems to be the Oak Ridge Boys cover version. However, the mega lesbians skip the verse and just sing the chorus after the opening line.
