Mr. Garrison claims he obtained a Masters Degree in mechanical Engineering at Denver Community College. (edit) When the investors are gathered to see "IT" you can see Bill Gates still has a bullet hole in his forehead from when he was shot in "South Park: Bigger Longer and Uncut" (edit) The alternative title for this episode, 'The Ginger Device', could be taken to mean 'The Queer Device' -
based on Cockney Rhyming Slang (originating in London, England), where "Ginger" is "Ginger Beer", rhyming slang for "queer"! [ Editor's note: An interesting concept, but in this case "Ginger" refers to the name of a real transportation device that was revealed in 2001 that had piqued the interest of some of the investors seen in this episode. You can search the web for more information on this device using the keywords "Ginger" and "transportation". ] (edit) This is the second time Mr. Garrison's first name is said to be Herbert. The first was in the episode "Worldwide Recorder Concert." (edit)

Kyle: You especially can't say anything about Jews.
Cartman: Oh Jesus why don't you just cut off my balls!? (edit) Stan: Dude, a self hating Jew? You are becoming a stereotype. (edit) News Anchorman: Here with the report is a Hispanic man with some gravy stains on his lapel. (edit) Kyle the super Jew: Why is it so cold in here? I mean I know we're in the mountains, but does that mean we have to freeze to death? (edit) Mr. Garrison: That's it! A gyroscope. It will allow for maximum balance and…Mr. Hat, you're a genius! (edit)

When Kyle's cousin says "Sorry about your sled", you can hear his voice sounds different. (edit) John Travolta seems to be different in appearance here than he was in the episode Trapped in the Closet, also, he speaks in a normal voice than his accent heavy tone. (edit) This is the first time that South
Park has ripped on a celebrity that they once worked with, Yasmine Bleeth. (edit) The person who tests out the "It" is Mr. Nommels, Craig's father. (edit) Response to the Kyle saying Jesus goof: Who cares if you're a Christian or Muslim (I am a Muslim) or Jewish, you can say Jesus is Jewish, and he is also mentioned in the Koran as a prophet. (edit)

Jimmy Neutron:

Mr. Garrison's vehicle IT is very similar to the ultra orb used in the Dec 2001 film, Jimmy Neutron: Boy Genius. (edit) Segway:

Businessman: We're going to have to re-think cities!

Mr. Garrison's invention is analogous to the Segway scooter that was widely publicized as a mystery invention that would "change civilization." One of the famous investors in the project (Steve Jobs I think) was quoted as saying something about how we would have to re-think cities based on this invention.

However, the scooter is pretty expensive and has not been nearly as successful as a lot of people thought it would. (edit) Hoveround:

Old Ladies: "IT"!

The scene with the two old ladies at the Grand Canyon with the narrarator asking them how they got to the Grand Canyon is a reference the the Hoveround wheelchair commercials in which two old ladies got to the Grand Canyon with them. (edit)
