Trivia
When Peter mentions his kids, along with the Nick at Nite line-up, he does not mention Meg, which is a running gag on the show. Her name is mentioned in the musical number shortly after.

Goofs
When showing Lee Harvey Oswald waving to John F. Kennedy and then later attempting to shoot at the "assassin" on the Grassy Knoll, Oswald is shown directing all of his actions to his left. In reality, both JFK and the Grassy Knoll were on Oswald's right from his window spot in the School Book Depository.

Quotes
Lois Griffin: [Lois and Peter wait for a pregnancy test] God, I can't believe we weren't more careful. This probably happened that night we tried role playing.
Lois Griffin: [flashback] Oh, I need a spankin'. I'm a bad, bad girl.
Peter Griffin: I'm a Paladin with 18 charisma and 97 hit points. I can use my helm of disintegration and do one D4 damage as my half-elf mage wields his plus-five holy avenger.
Lois Griffin: Paladin's can't use the helm of disintegration.
Peter Griffin: Oh. Then, I'm a black guuuuy.
