Continuity mistake: When Peter and Brian are trying to get close to Luke Perry, there's a shot of Luke at the pool and the camera pans over to him. In that shot, there is no drink on his table.

Continuity mistake: When Meg is walking by lockers with students reading the paper that has Meg's story in it, the lockers change between shots. They go from tall single lockers to double-stacked lockers. (00:13:23)

Suddenly, the family couch, that was seen in several shots before, is right up against the wall where the table should be and the house front door is missing. The circular rug at the foot of the couch is missing. (00:11:33 - 00:12:19)
Continuity mistake: After Meg gives Brian a copy of her report on Mayor West, he reacts to it and Peter takes a copy.

(00:11:44)
Continuity mistake: Lois takes away the box of Fig Newtons from Stewie and sets it on the counter in the kitchen.

(00:09:11)
Continuity mistake: When Meg walks up to Neil's desk, there is a cup of water on the side of the desk next to the paper, and Neil puts his hands on the paper near the edge. Then in the next shot, his hands move to the centre of the paper and now the cup of water is also on the paper. (00:06:34)
Continuity mistake: When Neil goes to wash his retainer at the water fountain, in the first shot there is no button on the fountain, but it appears in the close-up.

(00:11:45)
Continuity mistake: In the cutaway gag after Peter says he thought about selling his body to science, there is his skeleton in a classroom hanging up.

He's Too Sexy for His Fat - S2-E17
Continuity mistake: When Lois is trying to Get Stewie to eat some cake, there is a bowl on the table with flowers. In most of the shots, the bowl has 4 flowers in it.

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)
Peter, Peter, Caviar Eater - S2-E1
Continuity mistake: Making his point to Peter, Brian smashes his Star Was glass on the floor which snaps Peter out of his stupor. The glass shattered into many pieces on the floor in front of Peter's chair. In the subsequent shots, the broken glass is nowhere to be seen on the floor. (00:18:02)
Other mistake: Throughout many episodes, it's discovered that anybody that touches Death immediately dies. When Stewie learns that Death has come for Peter, he immediately touches his finger to lead him inside but manages to live.
Factual error: When Stewie writes in his notebook he actually never opens it.

Continuity mistake: When Brian is at the psychiatrist's for the first time, the psychiatrist's chair changes position between shots. (00:08:20)
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.
