Timmy picking out his turkey is like Charlie Brown picking that pathetic little Christmas tree in "A charlie Brown Christmas". He took it back to everyone else and they said "What the hell is that?", just like the SP gang did.
Timmy's house now has a second floor. Compare these two pictures:
"Timmy, we already got a turkey." --- Kyle is supposed to be saying these words, but it's Stan who's speaking.
The same crap Cartman always sees is a tribute to A Clockwork Orange when Alex comes home the first night and closes his eyes: 'And oh what lovely pictures I did see.' It is all violent stuff - hangings, explosions, Alex as a Vampire, etc. The Nazi footage is stuff that Alex is forced to watch later in the film.
The lyrics to Andrew Lloyd Webber's "The Phantom of the Opera" were written by Charles Hart, not Tim Rice.
The boy who asks why his mom died is Kevin, the boy thawed from the snow, from "Summer Sucks."
The girl who lost her dog Robby is Marcy, from "Probably."
The facts on Helen Keller (hint: her father's name was not John):
As Timmy moves down the business district he passes by Tele's. The big-screen TV is missing.
Timmy has a lot more going on in his brain than his body will allow to be shown.
Timmy performs a feat right out of In The Line Of Fire and other films when he dives out of his chair and takes a bullet for Gobbles.
When Gobbles goes to jump through the ring of fire, no waterworks are seen. But as he steps through it a fountain of water is seen in the background
The turkey mass murder scene "Our turkeys are killed humanely" comes from the movie Soylent Green.
Though Principal Victoria claps, there is no sound of clapping. Again at the end of the play, the audience claps but there was no sound.
This episode can be seen as a tribute to The Who's Tommy, as that musical focused on a a boy who is deaf, dumb and blind, and whose experiences lead to enlightenment and sainthood (of course, the big thing in the episode was Helen Keller learning what water is, the first step on her journey).
