Family Guy

The FOX ad for this episode featured the following dialogue:

Peter: You're not like over 40, are you?

Lois: What's wrong with women over 40?

Peter: Their bodies and personality.

This dialogue was not heard in the actual episode.

In the "black guy in Sweden" cutaway, they are talking German "blacken sie been" roughly translated to "he is black"

Peter: "It's the story of Christmas and the Immaculate Conception".

This is a common misunderstanding; what Peter means is the Virgin Birth. The Immaculate Conception refers to the dogma of Mary being free of the Original Sin when she was conceived by her mother Anne.

Lois is 43 years old.

Joe Swanson, himself, admitted that Kevin had died in Iraq in a previous season, But he is alive and well now.

The first episode with the cast being British and how their faces are made is the same design for the British family that was suppose to be in The Cleveland Show, but were written out because how the father and the son had impolite faces.

Bayit

'Bayit' is the Hebrew word for 'house'. As such, the title could be a reference to the Talking Heads song "Burning Down the House".

Stewie tells Brian that changing the past can alternate the future, but back in "The Road to Germany" Stewie tells Brian that they can do what they like in the past.

Future Brian tells the 1999 version of himself to write the Harry Potter novels. However, the first novel in the series was already published in 1997 and would have already existed in 1999. Therefore, Brian could not have written them.

Since the Stewie's time machine was blown up during the events of "Road to Germany", he must have built another identical time machine since that episode.

Quagmire claims that Cheryl Tiegs left him because he got jealous too easily. However in the episode, "And Then There Were Fewer," he claimed that she left him because James Woods stole her from him.

Brian and Cheryl Tiegs (and later Quagmire and Jillian) are seen dining in a restaurant called "l'Espèce d'Andouille." In French, "espèce de" translates to "stupid," and "andouille" is a slang word for "imbecile" or "idiot," making the name of the restaurant essentially "The Stupid Idiot" or perhaps just "The Idiot."

Chris did not appear in this episode.

Chris' birthday is February 8.

The song that Franz Gutentag is singing while moving a "Chris" puppet is "Der Kommisar" by Falco.

German used in this episode:
"Gutentag" means "good day", "Schlechtnacht" means "bad night".
The sign on the right door reads "keine entranz mit platz munchen" which means "no ... with place munich". "Entranz" isn't German.
The sign on the left door reads "gluck mach nicht enmechwerchtich lieber" which means "luck make not ... rather"; "enmechwerchtich" is gibberish.

The song "Mr. Booze" is from the movie "Robin and the 7 Hoods."

Near the end of the episode, Cleveland is watching the Quahog Channel 5 News, which he shouldn't have been able to do since he is in Stoolbend, Virginia.

Chris, Meg, and Stewie were not in this episode.

Brian has found the baloney while talking to Lois, after he has read whole book. He certainly should have found it earlier, during the reading.
