The Spirit of Christmas is a series of two Christmas shorts created by Trey Parker and Matt Stone. The two shorts are entitled Jesus vs. Frosty and Jesus vs. Santa, which were released in 1992 and 1995 respectively. The [in]famous animated series South Park spawned from these shorts.
In Jesus vs. Frosty, four boys who vaguely resemble the South Park main characters build a snowman, which comes to life when they put a hat on its head; unfortunately, it's Ax-Crazy, grows tentacles and kills proto-Cartman and proto-Kenny. The remaining two decide to ask Jesus (depicted as a baby with an adult Jesus' head) for help; he throws his halo like a boomerang at the snowman and knocks its hat off, rendering it lifeless.
In Jesus vs. Santa, the style is much closer to South Park, with the boys all looking like their selves from the show. Here, an adult Jesus descends from the sky and asks they to take him to Santa Claus; sure enough, the local Mall Santa is the real thing, and the pair begin to fight about whether the true meaning of Christmas is religion or giving. Ultimately, the boys get advice from Brian Boitano and help the two reconcile.
The shorts can be seen here and here; the latter can also be seen on the South Park The Hits: Volume 1 DVD, and, as a Mythology Gag, was featured in the plot of the episode "A Very Crappy Christmas." (Jesus vs. Frosty was briefly alluded to in "Simpsons Did It Already.")
Jesus vs. Frosty (1992):
- Early Installment Weirdness: A lot of the short's elements are dramatically different from how the show is nowadays.
- Early Installment Character-Design Difference: Cartman, Kenny, and Stan's character designs look the same as today, but Kyle's is completely indistinguishable; he is shown wearing a green jacket and a yellow cap rather than his modern day orange jacket and green ushanka.
- No Name Given: All of the boys except proto-Cartman, who's named "Kenny."
- Snowlems: The snowman that the boys build comes to life as an evil killer who has tentacles.
Jesus vs. Santa (1995)
- Early-Bird Cameo: Wendy makes a cameo as a nameless girl sitting on Santa's lap.
- Makes Just as Much Sense in Context: The boys' devotion to Brian Boitano, who randomly appears when they mention him.
- Politically Incorrect Hero: Cartman's Establishing Character Moment is mocking Kyle for being Jewish.
- Off with His Head!: Kenny is killed when a stray blast from Santa Claus ends up accidentally decapitating him.
- Recycled Script: Aside from the similar plots, it ends with the same speech about the meaning of Christmas being "presents."
- What Would Brian Boitano Do?: The boys ask themselves this, and Boitano appears to break up the fight between Jesus and Santa.
