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)

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.
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.
