'N Sync provided their own speaking voices but did not provide the singing voices for the Party Posse. Two members of another Lou Pearlman boy band, Natural, provided some of the voices -- Marc Terenzi for Nelson and Michael 'J' Horn for Milhouse.
This episode aired seven months before 9/11. During the scene in New York, the World Trade Center is briefly visible and there was a scene of a New York tower (the MAD Magazine main office) getting blown up.
Both episodes involve New York City, MAD magazine, the phrase "New Kids on the Blecch", and both episodes have been edited (or pulled from rotation) after the 9/11 attacks ("New Kids on the Blecch" merely had the scene of the MAD Magazine tower getting blown up cut; "City of New York vs. Homer Simpson" was temporarily banned, then heavily edited on a lot of local affiliates to remove most of the scenes of Homer at the World Trade Center).
A few seconds after L.T. Smash flips the switch on the aircraft carrier from "DE-COMMISSION" to "COMMISSION", the switch is again visible, but instead reads "MUSEUM" instead of "DE-COMMISSION" and "SHIP" instead of "COMMISSION".
This episode hints that Springfield is located on the east coast of United States, when L.T. Smash. Smash is able to drive New York City in the aircraft carrier.
At one point in the episode, a flag is depicted on the side of a technical employed by military fighters in Middle Eastern dress. The flag in the episode resembles the flag adopted by the Syrian opposition in the Syrian Civil War, but is actually the Independence flag. The resemblance was cited by some supporters of the Syrian government and media in the Middle East as evidence that the Syrian rebellion was a foreign plot.
While going over his checklist for the Party Posse, Lt. Smash has three things listed. The third thing says "Boogaloo... Electric". This is a reference to the 1984 film Breakin' 2: Electric Boogaloo, which featured the electric boogaloo dancing style, or the band of the same name that made it famous in 1977.
The video for "Drop Da Bomb" is apparently directed by Ang Lee.
In Mad Magazine headquarters, one man says "Why don't we call it Everybody Hates Raymond?", a reference to the CBS sitcom Everybody Loves Raymond. It should be noted that MAD Magazine actually did have an Everybody Loves Raymond parody in the 1990s called Everybody Loathes Raymud (and the animated sketch show MAD on Cartoon Network also had an Everybody Loves Raymond parody called Everybody Loves Rayman).
The way 'Yvan eht nioj' is pronounced in this episode would, if played backwards, actually sound like "join te nævi" and not like "Join the Navy". The characters pronounce the words the way they are spelled backwards, rather than by pronouncing the actual phoenetic sounds backwards.
When the singers sing "Yvan eht nioj," they hold the last syllable, "oj." When played backwards, they hold the last syllable of "Join the Navy," "vy."
L.T. attacks the MAD building with the Aircraft carriers missiles. No current carrier carries missile launchers (except on their planes).
Children jump off of the aircraft carrier and land in shallow water before walking to the shore. In actuality, to avoid scraping the bottom, the carrier would need water that was 25-40 feet deep (depending on what type/class of carrier).
The advance copy of MAD shown to L.T. by the general shows Alfred Neumann looking at the reader and the title reads "We flush the Potty Posse", parodying the bands name, yet the copy the boys pick up after MAD Headquarters was destroyed spells the name correctly and Neumann looks at the toilet now. Also the boys positions in the toilet have changed.
The switch that L.T flips has two modes, the mode its set to is indicated by signs above and below it. When he flips the switch, the signs say "Commission" & "DE-COMISSION" above and below respectively. However, when he moves away from the ship pointing his gun, the signs now say "SHIP" & "MUSEUM" respectively.
When the World Trade Center appears, the antenna on the North Tower is missing.
