Other mistake: When Peter and Lois begin to search for the black market, it then cuts to an exterior shot of Stewie's daycare. In this shot, not only is the entire left side of the chain link fence missing, but bizarrely, this missing gate still casts a shadow on the sidewalk. (00:18:40)
There's Something About Paulie - S2-E16
Other mistake: Peter walks into the living room and finds Lois on the couch. Just after he asks her if she's been drinking, she starts to sit up and then suddenly the entire episode starts bobbing up and down. Like the show is on a camera bouncing in a car. This lasts a couple of seconds then stops. I checked on Disney+, Hulu, and WCO. Each of these had the same camera jitters in that moment. (00:00:45)
There's Something About Paulie - S2-E16
Other mistake: Peter follows the mobster to the "pet store" and is standing on the sidewalk when the mobster gets out of his car and goes inside. The street here is comically disproportionately small. So much so that when Peter walks across it, he clears the entire road in two steps. (00:14:40)
There's Something About Paulie - S2-E16
Other mistake: After the car bomb destroys their new blue car, the groom at the wedding comes out to warn them too late, then runs off. As Peter and Lois are turning around in the next shot to walk, the cars behind them are disproportionally small, with the scaling being off here. (00:21:35)
He's Too Sexy for His Fat - S2-E17
Other mistake: After the cutaway with the lemonade stand not taking credit cards, the episode cuts to an exterior shot of the hotel that the Griffins are now staying in. For a large hotel like that, the parking lot is way too small, showing only two cars in the front with only three visible spots, and one car parked in the street behind the building. Far too few spots and far too few cars considering how many room lights are turned on. (00:05:50)
Other mistake: When Peter is digging a hole in his back yard, he uses his shovel to cut the power supply to all of Quahog. We see Joe watching TV and Quagmire messing with his sex doll. The power cuts off, and so then Joe's TV turns off and Quagmire's doll turns off. However, the lights in the rooms they are in stay on. The power being cut would have turned off the lights also. (00:05:32)
Other mistake: When Peter sits down with Mayor West to discuss terms, West says, "Thank you all for coming." As he does, he tilts his head down and the bottom half of his nose disappears until he moves his head again. (00:20:38)
The Thin White Line (1) - S3-E1
Other mistake: During the scene at the rehab clinic when Brian is jogging, Peter asks if he wants to go "mess with the pregnant teens across the lake." Brian says no because "Group therapy, two o'clock." However, the sky looks as if the sun is about to rise or just set. The time cannot be anywhere close to 2:00, neither AM nor PM.
Mr. Griffin Goes to Washington - S3-E3
Other mistake: In the cutaway to Mike Tyson during the baseball game, people in the crowd are missing their faces. (00:03:00)
One If By Clam, Two If By Sea - S3-E4
Other mistake: When the cops burst into the house we see the action on a TV as shown by the Quahog News logo in bottom left. However on the TV in the living room the logo is missing. It should be there as well. (00:12:45)
One If By Clam, Two If By Sea - S3-E4
Other mistake: After the hurricane passes, Peter acts like he's been impaled by a wooden plank. He pulls it out as if it was attached to his right side. However, the way the metal on the clasp was bent, the only way the wooden plank could've been positioned that way is if the metal was over his shoulder.
Death Lives - S3-E6
Other mistake: When Peter is dumped into the sea, a ship appears on the right hand side of the screen. However, the ship just appears randomly, it doesn't sail in to the shot, one frame its open water and the next frame it's there. (00:10:20)
Other mistake: When Lois knocks out the karate master, if you look in the stands, behind Peter, there is a person without a nose.
To Live and Die in Dixie - S3-E12
Other mistake: When Stewie is with his 'band' for the first time when he is tuning his guitar, the string he's tuning doesn't match the peg he's turning.
Other mistake: When Stewie asks if the sheep is being "baashful", the animation of the duck nearest the camera keeps repeating. Watch carefully and you will see 2 bits of grain moving backwards and forwards in a horizontal motion. (00:00:35)
A Very Special Family Guy Freakin' Christmas - S3-E16
Other mistake: When Peter runs over the manger with his car the camel flies towards the left out of shot, but when it falls on Peter it is falling straight down as if it was shot upward.
From Method to Madness - S3-E18
Other mistake: After the fight between Stewie and Olivia at the concert hall (followed by their breakup), Simon tells Stewie that the act without Olivia is "over" as he turns to walk off the screen. However, before Simon is even partially out of the shot, he completely disappears. (00:18:45)
Stuck Together, Torn Apart - S3-E19
Other mistake: In the scene where Brian gets off the phone with the glue company, he says the bad news is that the substance to remove the glue takes two weeks to arrive, but the captions read seven days.
Other mistake: The 'KISS' logo above Kiss's stage isn't actually held up by anything.
Other mistake: When Lois is saying about not having a spark in their marriage any more, the headboard of the bed keeps changing shades from light to dark in very quick succession. (00:03:00)
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.
