- Actor Allusion: Schnitzel the reindeer's song "We're Not So Bad" starts off sounding vaguely like "Everybody Hurts" by R.E.M.. Schnitzel's voice actor is Michael Stipe, the band's lead vocalist.
- Creator Cameo: Matt Groening voices Arturo, the elf that Schnitzel accidentally throws Olive into during the bar scene.
- Creator's Oddball:
- Descended Creator:
- Producer Drew Barrymore voices the special's title character.
- Executive producer Michael Stipe provides the voice of Blitzen's flightless cousin Schnitzel.
- Truth in Television: The postman's worry isn't without merit. By the time the holidays roll around, people do use the postal service a lot more frequently to the point they start hiring seasonal helpers just to lighten the load.
- Unintentional Period Piece: Subverted. Martini mentions he'll root for Olive on Court TV. While Court TV was rebranded as truTV in 2008, which was nine years after the special was released, the relaunch of Court TV in 2019 no longer makes the special this trope for the time being.
