This episode is sometimes also referred to as "A Hey Arnold Christmas".
According to Mr. Hyunh, candy is bad for his stomach.
The inscription on the Federal Office of Information reads in Latin, "Cave, Quivi Sumus". In English, this loosely translates to "Beware, whoever we are".
Unlike most other Christmas specials, especially non-animated ones, nobody in this episode sings a Christmas carol.
Also, unlike most other Christmas specials, Santa Claus isn't featured or even mentioned in this episode.
This is one of two episodes where Olga appears but doesn't cry (the other being "Helga on the Couch").
Steve Lowtwait has said that this episode was one of the most endearing things that he has ever worked on[citation needed].
The truck that says "Stark's Moving Company" is a reference to storyboard director Stark Howell.
The store Helga finds the videogame in is called "Budnick's Department Store", after background painter Alfred Budnick.
Animation from "Snow" is reused at the start of the episode.
Much of the snowfall effects were done with live-action snow superimposed over the animation. This is an old animation technique that was often used by Disney[citation needed].
This episode originally had a dream sequence of Arnold flying from his bed in the boarding house to Vietnam, which was cut for time.
Airing[]
Though it was a Christmas Special, it originally aired two weeks before Christmas Day, a recurring trend with many holiday specials as years went on.
The last time this episode aired on the main Nickelodeon channel is December 6, 2007.
This episode never reran on The Splat until Christmas 2016.
Cultural References[]
This is the first episode to relate to a real life event such as the Vietnam War, although this is never explicitly stated in this episode.
Mr. Hyunh comes from Vietnam, as mentioned in "Snow".
Mr. Hyunh mentions the "war in the North". The Vietnam War started when the North section of Vietnam became communist and declared war on the South half, which was capitalist.
The scene when Mr. Hyunh gives Mai to the American helicopter leaving the city mirrors the real-life famous image of the helicopter taking refugees out of Saigon (called Ho Chi Minh City as of July 1976) after the South was conquered by the North.
When Helga overhears Arnold talking about his mission to reunite Mr. Hyunh with his daughter, a sign behind her says "Saigon Helicopter".
Mr. Hyunh mentions he had to wait 20 years to come to America. It wasn't until liberation of the Vietnamese Communist Government in 1995, 20 years after the Fall of Saigon, that people could leave the country.
This also means Mr. Hyunh likely arrived in Hillwood not long ago, if this episode is considered to be set on 1996.
Mr. Hyunh's voice actor, Baoan Coleman, was at the real Fall of Saigon in Vietnam.
The department store Kacy's is based on the real-life store chain Macy's.
The character of Mr. Bailey may possibly be a reference to George Bailey - the protagonist played by actor James Stewart in the 1946 film It's a Wonderful Life.
Stewart was nominated for the Academy Award for Best Actor in this film, now turned into a holiday favorite.
It's a Wonderful Life is itself based on A Christmas Carol, a classic book turned into a Christmas favorite.
After a heartfelt speech, Gerald tells Arnold, "That's what Christmas is all about, Arnold", a reference to Linus's line "That's what Christmas is all about, Charlie Brown" from A Charlie Brown Christmas.
According to Craig Bartlett, numerous Peanuts specials were a huge influence in the creation of Hey Arnold!.
Continuity[]
This episode begins a running gag in which Grandma gets her holidays mixed up.
In this episode she celebrates Thanksgiving on Christmas Eve and New Year's Day on Christmas Day.
The scene where Helga looks at Arnold through her window and wishes him a Merry Christmas from outside, mirrors the end scene of Helga's story in "Arnold's Thanksgiving", when Arnold stands outside her house and wishes Helga a Happy Thanksgiving.
Story Analysis[]
Helga picks up Mr. Bailey's shopping list thinking its Arnold's, so she follows him to figure out if the Nancy Spumoni's snow boots listed could be Arnold's present for her. She is later surprised when she learns about the real owner of the list.
Helga standing in the snow outside the boarding house could be explained by she guiding Mai there (as neither Mai nor Mr. Bailey would know where Mr. Hyunh currently lives at).
Morals[]
It is better to give than it is to receive, which is what Christmas is all about.
