|List of Pop culture references
|References to popular culture in this episode:
- Shout out:
- "Baby Boomer Santa" includes many references including: Coca Cola, Doris Day, The Beatles, Woodstock, "Staying Alive," Steven Spielberg, Gremlins, MTV and Twin Peaks.
- Jeff refers to Mr. Radison as "equal parts Hanson and Manson."
- Use your allusion:
- "Christmas Infiltration" has Abed singing the line: 'If years were seasons, this December would be the December of our December." In a Tweet, Dan Harmon explains this line: "If years, which contain 4 seasons, were seasons in a 4 season story, winter of season 3 would be the coldest and darkest." This is not only a reference to the overall story arc of the show but also to the fact that this episode is the last one shown before NBC put Community on an extended mid-season hiatus.
- During Troy and Abed's rendition of "Baby Boomer Santa" Annie, Britta And Shirley reenact the "Three Wise Monkeys "Hear no Evil, See No Evil, Speak No Evil".
|List of Meta references
|Meta references in this episode:
- Donald Glover used to be a practicing Jehovah's Witness which is referenced in the rap his character Troy does with Abed.
- Jeff saying "Not liking Glee doesn't make us bullies" is a reference to Glee creator Ryan Murphy's comments about musicians and bands who refused to have their music featured on his show. This is referenced again when Mr. Rad shouts "Look, Kings Of Leon!", which is the name of one of those bands.
- The entire episode is a parody/satire of the popular Fox show Glee with a few scenes done in the same style, along with many overt references to the show such as the harmonizing vocals heard in the background of certain scenes.
- Along with Glee, the episode also parodies Invasion of the Body Snatchers, in particular, the 1978 version, starring Donald Sutherland. The parody is centered around the theme of people who you are close to being subsumed by an outside force, to the extreme that they're not the same person anymore. The most direct reference to Body Snatchers is when Jeff turns Britta, holding his hand out and singing, mirroring Donald Sutherland's behavior in the film .
- The song "Baby Boomer Santa" has Troy and Abed mimicking certain singing styles including Elvis Presley and Bob Dylan. They also do dances similar to John Travolta in "Staying Alive" and Courtney Cox from Bruce Springsteen's "Dancing in the Dark" video.
- The song Annie sings "Teach Me How to Understand Christmas" is a satire of similar holiday classics with lyrics that reflect the criticisms of those type of songs. In this interview, the writer of the episode Megan Ganz explained: "That song too was supposed to be a satire of the way that those "Santa Baby" songs infantilize women’s sexuality. Of course, it’s Alison Brie doing it, so it’s going to be sexy."
- The Inspector Spacetime Holiday Special is a parody of the infamous Star Wars Holiday Special, which aired only once in 1978. While intended for rebroadcast, the universal negative reviews canceled any further distribution. Included in the special are several holograms of bands such as the one seen in Inspector Spacetime.
- Résumé: Years ago, Alison Brie did an online skit singing "Santa Baby," wearing a similar outfit and performing the song just as provocatively as she did in "Teach Me How To Understand Christmas."
