Stewie: Ohhh! She has the voice of an angel...not to mention a balcony you could do Shakespeare from!
(Stewie's Letter) Dear stupid dog, I've gone to live with the children on jolly farm. Good bye forever. Stewie.
P.S. I never got a chance to return that sweater Lois gave me for Christmas. Umm, I left the receipt on top of my bureau. I'm probably over the thirty day return limit but umm… I'm sure if you make a fuss they'll at least give you a store credit or something. Umm.. It's actually not a horrible sweater. It's... It's just I can't imagine when I would ever wear it you know? Oh I also left a button on the bureau. I'm not sure what it goes to, but I can never bring myself to throw a button away. I know that as soon as I do I'll find the garment it goes to and then it'll… Wait a minute, could it be from the sweater? Did that sweater have buttons? Hmm… Well I should wrap this up before I start to ramble. Again, goodbye forever.
P.P.S. You know, it might be a little chilly in London, I'm actually going to take the sweater.
(Brian and Stewie are on a German tour bus.)
German Tour Guide: You vill find more on Germany's contributions to ze arts in ze pamphlets ve have provided.
Brian: Yeah, about your pamphlet... uh, I'm not seeing anything about German history between 1939 and 1945. There's just a big gap.
Tour guide: Everyone vas on vacation. On your left is Munich's first city hall, erected in 15...
Brian: Wait, what are you talking about? Germany invaded Poland in 1939 and...
Tour Guide: We were invited. Punch vas served. Check vit Poland.
Brian: You can't just ignore those years. Thomas Mann fled to America because of Nazism's stranglehold on Germany.
Tour guide: Nope, nope. He left to manage a Dairy Queen.
Brian: A Dairy Queen? That's preposterous.
Tour guide: I vill hear no more insinuations about the German people. Nothing bad happened. Sie werden sich hinsetzen. Sie werden ruhig sein. Sie werden nicht beleidigen Deutschland. You will sit down. You will shut up. You will not insult Germany. (Throws his hand up in a Hitler salute.)
Brian: Uh, is that a beer hall?
Tour guide: (Snapping out of it) Oh yes, Munich is renowned for its historic beer halls.
Brian & Stewie: You and I are so awfully different, too awfully different, to ever be pals.
Stewie: Do you want to go first.
Brian: Yeah I'll go, your favorite hero is the Marquis De Sade.
Stewie: Oh your one to talk, you got a stiffy from Phylicia Rashad.
Brian: Oh one time
Stewie: I have a style flair, just look at my hip hair.
Brian: Oh yeah thats quite a nice due there.
Stewie: Oh thanks
Brian: For me to poop on!
Brian: Oh come on you look like Charlie Brown.
Stewie: Oh bite me snoopy.
Brian & Stewie: Theres not a whole lot that we got to agree on..
Brian: Cause I love the strains of a classical score.
Stewie: And I like that singer who looks like a whore.
Brian: Ricky Martin?
Stewie: Love him
Brian & Stewie: Were too different to ever be pals...You and I are so awfully different, too awfully different, to ever be pals.
Brian: Your heads as massive as a meteorite.
Stewie: Oh very funny...you have a weenie like a christmas tree light.
Brian: I bet money, you'll marry a honey, who's pretty and funny, and her name will be Ted.
Stewie: Oh a gay joke.
Brian: I just work with what you give me.
Brian & Stewie: You might think were in sync but we stink, as a duo..
Brian: Cause you get a kick out of carnege and guts.
Stewie: And you get a kick out of stroking your...
Brian: Whoa whoa whoa, you cant say that on TV
Stewie: What, ego?
Brian & Stewie: Were too different to ever be pals!
Peter Criss, the drummer of KISS, has black hair the first time we see him at the concert. It then changes to yellow the second time we see him, then black again after that.
Peter and Dave compete with one another at KISS trivia and mention the band's appearance on "The Paul Lynde Halloween Special" from 1975. The show actually aired in 1976.
In the scene when Stewie says farewell to Brian at the doors of "Jolly Farm Revue", as he says "Well, this is it." Two plain brown doors are visible. After a cut to Brian, Stewie starts to walk inside and, suddenly, there are two handles on the doors, right above Stewie's head.
When Stewie (who is stoned) sets his fork on the table in the coffee shop, it disappears afterwards.
A scene at the KISS concert shows Peter Criss having blond hair and wearing a shirt with no sleeves. But in a scene afterwards, his hair changes to it's normal color, black, and he is wearing a shirt with sleeves.
At the scene where Brian and Stewie are on a tour bus in Germany, you can see that in one shot, the color of the tour guide's microphone is black. However, in another shot, the microphone is red.
After Peter warns Chris and Meg about the Candy Tree, in the next scene the girl the tree eats appears suddenly instead of walking from off screen.
When Stewie first spots a line of children whom he thinks they are going to London, the girl in the red jacket is carrying a bag and the boy in the brown suit is carrying nothing. However in the next shot, the girl is carrying a doll and the boy is carrying a suitcase.
When Stewie starts to follow the children thinking they are going to London, the buttons on his overalls change from grey to yellow.
The camel salesman says that one of his camels was "only driven to mosque on Sundays" by its previous owner. It is more likely that the owner would have traveled to the mosque on a Friday.
When Lois introduces herself to KISS, the closed captions misspell her last name as Buderschmidt instead of Pewterschmidt.
Lois recognizes Gene Simmons as Chaim Witz (his birth name); however Simmons took the name Eugene (or Gene) Klein, his mother's maiden name, after emigrating to the US when he was only 8 years old. So it is unlikely she would know him as Chaim.
