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.
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.

Plot hole: Brian has a 13-year-old son. Not possible since Brian has only lived 7 years.

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.

Stew-Roids - S7-E13
Continuity mistake: When Lois is talking to Meg on her bed she gets up and throws a book and a bottle of pills on the bed that came out of nowhere. The nightstand is out of view but if you look at the earlier scene there's nothing on the stand except a clock and a lamp.

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.
