Continuity mistake: When Peter goes back in time the first time, we see him and Cleveland slapping hands around the pool, we see that the pool is significantly shorter than in the scene where we first see Lois.

Boys Do Cry - S5-E15
Factual error: When Brian fires his pistol in the air, eventually killing the Super Devil, we hear six gunshots, each followed the distinct clink of the ejected cartridge hitting the ground. Trouble is, Brian is firing a revolver, which does not eject the cartridge after the bullet is fired. Only automatics do that.

Continuity mistake: At the very beginning of the episode, when we first see Peter and co. at the golfcourse, Peter and Quagmire get a lot closer between shots. (00:00:30)
Other mistake: Peter goes back in time and sees Lois at age 18. Death says everyone will see Peter as being 18 too. Problem: Lois and Peter aren't the same age. In later episodes, Lois reveals she's 2 years older than Peter so Peter should be 16 when he meets Lois.

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.
