This was the final episode produced prior to the show’s cancellation, though not the final one aired.
This episode’s theme is similar to “Road to Rhode Island,” a Brian/Stewie road-trip caper from season two. The starting credits are similar in style to the ones seen in Looney Tunes cartoons from the 1950s.
While on a bus top tour of Munich, Germany, Brian notes that the tour company’s brochure includes no information on German history from 1939 to 1945, the time of the Third Reich; the tour guide claims that Germany went on vacation for those years. Brian and the tour guide also argue about German novelist Thomas Mann. According to the tour guide, he went to America to manage a Dairy Queen, which is in reality what some WW2 veterans did when they returned. The tour guide gets furious at the accusations Brian makes and says in German “You will sit down! You will shut up! You will not insult Germany!” while using the Nazi salute. Although the vocabulary is right, the word order in his “You will not insult Germany!” is incorrect. An English accent is also clearly audible, indicating that the voice is not from a Native German speaker.
The phrase "Sie werden nicht Beleidigung Deutschland" isn't just incorrect word order. While still clumsy, it should be "Sie werden Deutschland nicht beleidigen!".
Near the end of the Munich scene, Brian mentions the beer halls, which the tour guide acknowledges. Munich was home to Adolf Hitler's infamous and ill-fated Beer Hall Putsch.
The BBC headquarters is depicted as a rectangular skyscraper. In fact, Television Centre is a low-rise, “6”-shaped building
The German flag on Munich’s tourist guide is missing its black bar.
After Paul Stanley and Gene Simmons storm off the stage, Peter Criss and Ace Frehley sing "Chattanooga Choo-Choo".
Dennis DeYoung, former lead singer of the band Styx, calls into to KISS Forum to badmouth KISS. The host threatens to play Styx’s 1977 hit “Come Sail Away” and then KISS’s 1976 song “Detroit Rock City” to see how they compare.
On the plane, Stewie and Brian appear to be seated next to 60 Minutes commentator Andy Rooney and comedians Jerry Seinfeld and Andy Dick after asking how the trip could get any worse. All of these comedians respond to this by saying lines that they have said previously.
During their musical number, Brian compares Stewie’s hair to that of Peanuts character Charlie Brown and Stewie compares Brian to Brown’s beagle Snoopy. The song also mentions Latin pop star Ricky Martin, French writer the Marquis de Sade and Triumph, the Insult Comic Dog, a puppet character from Late Night with Conan O’Brien. The song also has Brian claiming that Stewie’s gay, a running joke in the series.
