Well, that was... interesting. What was the Lemmiwinks minstrel songs a reference to? I hope they don't do a spinoff show with just Lemmiwinks like they did with Terrance & Phillip. And did anyone else go "Aw!!!" when they showed Mr. Slave's bunghole? Awww!!!!!
The song definitely sounds like it was inspired by "The Greatest Adventure" from the Hobbit. While this is the second Tolkien joke in three weeks, this is yet another Rankin/Bass homage by the bad boys of South Park.
Chef's Salty Balls: When Mr. Hanky is dying, there's a sad rendition of the Mr. Hanky song. That is a parody of Frosty of Snowman when a sad rendition of the song is sung after Frosty melts in the greenhouse.
Sexual Harassment Panda Bear: The Island of Misfit Safety Mascots (or whatever the place is called) is a play of the Island of Misfit Toys from Rudolph.
Mr. Hanky's Christmas Classics: As someone has already pointed out, the mailman character at the beginning of the episode is an homage to Fred Astaire's character in Santa Claus is Coming to Town (and the follow-up, the Easter Bunny is Coming to Town).
Wacky Molestation Adventure: Kyle's letter to Castro spoofs the "Blue Christmas" letter that a girl sends to Santa in The Year Without a Santa Claus.
A Very Crappy Christmas: The episode is a direct parody of 'Twas the Night Before Christmas, specifically: -the plot (an attempt to bring the Christmas spirit back to a town that has lost it) -the poo family (a parody of the the mice family, including the idea of the eldest child question Christmas) -the Spirit of Chirstmas film (it's use in the episode paralells the clock that plays a song that welcomes Santa at midnight on Xmas, right down to it breaking down and being fixed up by the mice/poo) -the song "Even a Miracle Needs a Hand"
Tolerance Death Camp: The Lemmiwinks song is inspired by "The Greatest Adventure", the theme song for the TV-movie the Hobbit.
I *love* that one. Especially the single shot of Kyle's face changed into the face of the main character in that song, complete with long nose and doe eyes! Funny stuff!
