Continuity mistake: Stewie floats over to Chris sleeping on the couch. Next shot shows Stewie getting tangled in the ceiling fan although there wasn't ever one in the living room.
Ready, Willing, and Disabled - S3-E15
Continuity mistake: Chris takes Meg's purse and throws it to Stewie to go through. He throws items on the floor, and when Meg takes her purse back, the items on the floor are not there.
And Then There Were Fewer - S9-E1
Plot hole: Every time someone dies, Diane is never in the room with everyone else, and they never notice she's always missing during the murders.
Continuity mistake: After Mayor West enjoys eating the taffy, when it cuts to the Griffin family standing on their lawn, the post-mounted mailbox is placed on the right side of the front door's walkway, but then it switches to the left side of the walkway.
Other mistake: When the family gets to the top of the mountain Brian goes left off-screen to pee. Lois says "we proved we aren't second best." Wideshot shows the Fishmans sitting there. They would've all seen them when they got there, yet they are shocked when Ross says "Well look who finally got here." And they are only inches apart.
Continuity mistake: After the LASIK surgery Lois has bandages covering her eyes, and the pairs of crisscrossed tape switch their over-under positions within the same shot.
Continuity mistake: When Meg, as X-Men's Quicksilver, starts to spite her whole family at the speed of light at the beginning of the episode - just after Chris sneezed in front of everybody - she initially throws his hat away from him, but in the next shot when she gets back on her seat, Chris' hat returns resting to his head.
Baby, You Knock Me Out - S9-E5
Continuity mistake: Peter sets his globe on the table beside the box it came in and walks over to Joe and hugs him. Next shot shows the globe back in the box on the couch even though you see the edge of the box the whole time.
Space Cadet - S11-E9
Revealing mistake: When Chris is giving them a tour of the shuttle, they are standing up normal. When they take off, they are still standing straight up. The shuttle goes straight up. You would be on your back at take off. They would never be able to stand straight up.
Petergeist - S4-E26
Other mistake: The Griffins' house disappears when they flee, but when they go to Quagmire's house after, you can see their house when they are at the front door. Quagmire's house is on the right of theirs and the angle of the shot is to the left so it's definitely their house, not Quagmire's other neighbours on his right. (00:16:36)
There's Something About Paulie - S2-E16
Continuity mistake: A mob member at Cleveland's deli offers to help Peter get a new car by stealing the used junker he bought and have insurance get him a new one. The new blue car he receives appears to resemble a Volkswagen Beetle when it first appears, but in the second shot the car's body is more Mercedes-like. (00:05:17)
Road to the North Pole - S9-E7
Other mistake: Cleveland's house, across the street from the Griffins, is absent in the opening overhead shot. Then the scene changes to inside, and we can see his house through the window.
Continuity mistake: Peter, Quagmire, Cleveland and Joe are crawling through the air duct. Joes wheelchair is nowhere in sight yet when they fall to the floor it hits Joe in the head. (00:10:18)
Factual error: If one of a person's parents is an American citizen, that person has citizenship no matter where they are born. Since Thelma was a U.S. citizen, that makes Peter a citizen of the U.S. Also, were there no tax records for Peter since he had been married to Lois?
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.
Continuity mistake: When Jesus first sits down and starts talking to Jay Leno, there's a coffee cup on his desk with the handle facing to the right. After Jesus says he's been playing Call of Duty, the cup has moved closer to Jesus with the handle facing to the left even though no one touched it.
A Very Special Family Guy Freakin' Christmas - S3-E16
Continuity mistake: Prior to the family opening their presents at the end of the episode, there is a shot of the outside of the home. Notice the right window intact. Cut to a shot inside, the window is still damaged from earlier in the episode.
Brian's Got a Brand New Bag - S8-E4
Continuity mistake: Towards the end of the episode, we see Rita's bedroom door opens in. When Brian returns from the store, there's no door at all. When he leaves, the door opens out because he slams it shut.
And Then There Were Fewer - S9-E1
Other mistake: When they are chasing Tom around the dining table, they huddle up in a circle. Everyone is looking at Peter talk, and when Doctor Hartman says "Damn, that is awfully risky," if you look at Carl's eyes, they clip outside their eyes to look at Hartman.
Continuity mistake: At the end of the episode, Connie kisses Stewie. Her book and Stewie's clothes disappear from the floor when Connie is taken away.
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.
