The Secrets of
"Imaginationland: Episode I"

The name of the guy with the blimp is Dreamfinder from EPCOT's Imagination pavilion.

This is a Wonder Showzen episode, as Vernon Chatman is back in the fold. The Imagination Song was originally sung in that show.

Kyle:That's not being nice! That's just putting on a nice sweater!General:Those aren't ideas, those are special effects!
Cartman:...I don't understand the difference.Michael Bay:I... don't understand the difference.
Kyle:I know you don't.General:I know you don't. Get him out of here!

The intense scene where Stan was dazed until Kyle arrived was taken from Saving Private Ryan. The same with Ronald McDonald retrieving his severed arm.

M. Night Shyalaman is turned down because his pitches are nothing but plot twists. Michael Bay is turned down because his pitches are nothing but special effects. Mel Gibson is approved! The man knows story structure!

"Maybe it's time for us all to just... get along." - refers to Rodney King's call for camaraderie at the height of the 1002 riots: "People, I just want to say, you know, can we all get along?"

"They are coming..." - One of Gandalf's lines from The Lord of the Rings: The Fellowship of the Ring.

The last scene before the credits was from Rambo: First Blood, with Cartman dressed as Rambo. I don't know where the music is from.
