A Very Crappy Christmas/Trivia

Trivia

 * It was revealed in this episode that Stan has blue eyes and black hair.
 * The animated Christmas card was actually one of the pilots of South Park, it is called Jesus vs. Santa
 * This is one of the few times that we see what Kenny wears to bed; in "Cartman Joins NAMBLA" (and most later episodes) he is seen wearing his parka to bed, but in South Park: Bigger, Longer & Uncut, Kenny wears only a pair of white briefs. In this case he is wearing both: he has the briefs on with the parka unzipped (although he was rushed out of bed by Kyle, so he could have just thrown it on in a hurry).
 * "The Circle of Poo" is a parody of "The Circle of Life" and "We are One" from the Lion King, the first and the second.
 * When Stan and Kyle are doing the voices for the special, they read lines from the part of the play after Kenny was killed. Later in the song we see that Kenny is killed, but then Stan and Kyle say they will kill him off in the film, implying that the events of the song aren't in order.
