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.
Continuity mistake: As Peter makes a comment on Jesus' joke, the screen goes into a closeup between the two of them. The potatoes on their plates change from a sandy yellow to white and the next time their plates are in view, the potatoes are back to their original colour. (00:11:33)
Continuity mistake: Peter is sitting in the audience with a blue jacket on. Next scene shows him come out of the building not wearing the jacket.
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.
