During the first airing of this episode, when the Middle Eastern man is yelling at his son about the hot air balloon, the boy says "but mother" instead of "but father."
On a close-up of Peter Criss during KISS's on-stage show, the drummer has blonde hair for one shot.
The German shouted by the Tour Guide when Brian raises questions about World War Two translates to, "YOU WILL SIT DOWN! YOU WILL BE QUIET! YOU WILL NOT INSULT GERMANY" although the grammar is not quite correct for this context.
Stewie: (Crawls inside a camel and gags) Oh God, I just threw up in his lung!
Chris: Dad, can Meg and I stay up late when you're away.
Peter: You can do whatever you want, Chris, just stay away from the Candy Tree.
Candy Tree: He's right to caution you. I feed off of children.
(Candy Tree eats a little girl)
Meg: I can't believe my stupid parents are gonna spend five days following stupid old Kiss around! it's painful!
Peter: Not half as painful as a tire iron upside your head.
Peter: I'll miss you!
Lois: Peter, are you ever gonna forgive me?
Peter: Lois, I am obligated to keep loving you, so I will take my rage out on my own body. Let's go to Denny's.
Peter: Lois, I'm packing for Kissstock and I can't find my favorite underwear!
Lois: You mean the one with the hole in the left butt cheek from you tore them pulling them up in the airplane bathroom when you had the trots?
Peter: No, the one with the hole in the right butt cheek from when I held it in during the extra-long sunday service mass because I thought blowing gas would offend Jesus, and I let it go in the vestibule, and it sounded like Louis Armstrong?
Lois: Oh. Middle drawer!
(As Stewie watches Jolly Farm Revue)
Brian: How can you stand watching this? It's dreck, and you know it. Oh, no response? No intelligent defense of this unmitigated crap?
Stewie: Commercial! (Kicks brian in the nuts, then walks off) I'm gonna get some Graham Crackers!
Brian: I'm stuck on a trans-atlantic flight with a petulant runaway. Could this get any worse?
Andy Rooney: You know what I hate about flying? The peanuts. First of all, you can't open them. Who are they trying to keep out of these?
Jerry Seinfeld: And what's the deal with the razor blade slot in the bathroom? Are people actually shaving in there?
Andy Dick: Hi, Andy Dick here. I just need to get my luggage into the overhead compartment here. (Items start falling out of the compartment) Whoa, that's whacky!
Peter: My wife 'did' KISS!
Announcer: Get out!
Lois: Hand to God...
KISS (singing): I'm gonna rock and roll all night...
(places the microphone in front of Lois to continue)
Lois (nervous): And... have a wonderful... time?
Stewie: Spit spot, Albert Hall, meat and two veg, Big Ben, Dave Clark Five, Spam and eggs, a baby's arm holding an apple, pip pip, cheerio.
German Tour Guide: Besides its beautiful, historic architecture, Munich was the home of many great writers, such as Thomas Mann. You will find more on Germany's contribution to art in the pamphlets we've provided.
Brian: Yeah, about your pamphlet... I'm not seeing anything about German history between 1939 and 1945. There's just a big gap.
Tour Guide: Everyone was on vacation! On your left is Munich's first city hall, erected in 15...
Brian: Wait, wait. What are you talking about? Germany invaded Poland in 1939 and...
Tour Guide: (screaming frantically) We were invited! Punch was served! Check with Poland!
Brian: You can't just ignore those years. Thomas Mann fled to America because of Nazism's stranglehold on Germany.
Tour Guide: No, no, he left to manage a Dairy Queen.
Brian: A Dairy Queen? That's preposterous.
Tour Guide: I WILL HEAR NO MORE INSINUATIONS ABOUT THE GERMAN PEOPLE!! NOTHING BAD HAPPENED!! (begins shouting in German)- SIE WERDEN SICH HINSETZEN, SIE WERDEN RUHIG SEIN, (raises his hand in Nazi salute) SIE WERDEN NICHT BELEIDIGEN DEUTSCHLAND!!!
(eveyone looks at him terrified)
Brian: (hesitantly) Uh, is that a beer hall?
Tour Guide: (cheerfully) Oh, yes! Munich is renowned for its historic beer halls.
Cardinal: Pope! Time to get up and put your hat.
Pope: It's a stupid hat.
Pope: Okay, okay. God!
(Goes into the bathroom, comes out, and drops his boxer shorts on the floor)
Cardinal: Pope, the floor is not a hamper.
Brian and Stewie's song
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 do 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 carnage 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: Never mind
Brian & Stewie: Were too different to ever be pals.
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.
This is the second time that Brian and Stewie get lost while on a long trip to somewhere, the first time being in episode "Road To Rhode Island".
Sometimes known as European Road Show
The DVD shows us a deleted scene in Paris, where Brian and Stewie visit Jim Morison's grave.
The opening credits are much like the ones in "Road to Rhode Island" which are a take off of old 40's movies.
When Brian and Stewie are entering Amsterdam, the bridge they cross is from a famous painting by Vincent Van Gogh, The Langlois Bridge at Arles (Amsterdam).
When Stewie is boarding the plane, he turned and raises his hands in a "v" sign. This was a characteristic gesture by President Richard Nixon.
Peddler: You like movies? I have "Dude, My Car Is Not Where I Parked It, But Praise Allah We Are Not Hurt".
This is a reference to the film Dude, Where's my Car?
Star Wars: The Empire Strikes Back
The idea of slicing open the camal and sitting inside it for warmth was a homage to The Empire Strikes Back when Han Solo sliced open the Tauntaun to protect himself and Luke Skywalker from the cold.
Peter Criss, Ace Frehley: Pardon Me, Boy Is that the Chattanooga choo-choo, Track 29, Boy you give me a shine
This is a song sung by the Glenn Miller Orchestra, which is oddly out of place sung by two members of KISS
Marquis De Sade
Brian: Your favorite Hero is the Marquis De Sade
The Marquis De Sade was a famous sexual pervert
Tour Guide: Oh yes, Munich is famous for its beer halls
In the scene where Brian enrages his German tour guide, Brian points out a beer hall and the tour guide goes off on that. The scene has very much to do with Nazis and Hitler, and so does the beerhall refferance. Late in 1923, Hitler and his Nazis attempted a coup in Munich, and did so by taking German government officials hostage in a beerhall. The whole thing was put down but its influence lived on and TIME magazine noted it as one of the 80 most important days in the last 80 years. This refferance might not be intentional, but it does work and it is sort of a neat fact
Triumph The Insult Comic Dog
Brian: Thats a nice do, for me to poop on.
This is a classic line from Triumph the Insult Comic Dog on Conan O'Brien.
