When You Wish Upon a Weinstein - S3-E22
Audio problem: When Peter sings "I Need A Jew", his mouth doesn't match the lyrics when he sings the line, "I don't think they killed my Lord"; this is because the original line, "Even though they killed my Lord" was considered too anti-Semitic.
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.
