Beginning with episode and continuing for all of the season 7 episodes, during the theme song, Kenny sings: "Someday I'll be old enough to put my d*ck in Britney's butt." (edit) The head alien (Nagix) turns into different formations. First, he's Randy Marsh. Second, he's a hideous monster (his true form), then Santa Claus, Michael Jordan, Don King, Mr. Roarke and Tattoo from "Fantasy Island," then George Burns, J.J. Walker of "Good Times," Saddam Hussien, then Missy Elliot, Frank Sinatra, and finally Cartman suggests that he should turn into a taco that craps ice cream. (edit) When Chef says "Who's having butt sex?" the next scene shows the alien in the form of Saddam, as if to answer his question. (edit) In yet another bit of self-deprecating humor, the network heads say that a show should not go past 100 episodes because then the plots and settings get awful and ridiculous. Although this episode aired as the season premiere, it was written to be the 100th episode. (edit) The Gilgamecks from the "Red Hot Catholic Love" episode are mentioned in the reality show "Who Wants to Marry a Gilgameck?". (edit)

Nagix: Hello boys.
Stan: Dad?
Nagix: No, not really. I just read your mind and thought this form might be more pleasing to you.
Kyle: Oh dude, don't do that, that's gay.
Stan: Yeah, that's like that stupid movie Contact.
Cartman: Ah, God that movie pissed me off. (edit) Proctologist: What seems to be the problem?
Chef: We just want you to take a look and tell us if you see anything abnormal.
Kyle: Other than its monstrous size.
Cartman: SHUT UP KYLE! SHUT YOUR GOD DAMN MOUTH! (edit) Cartman: (grunts) I'm trapped inside Helen Hunt's ass! Oh god, help me you guys!! (edit) Kyle: No Ike, you can't go to school!
Cartman: (to Ike) Yeah go home you little dildo!
Kyle: For the last time! Don't call my brother a dildo!
Cartman: Alright, go home you little semen puking asshole dickhead. (edit) Chef: Where did you learn to drive aliens?! Chinese auto school?! (edit)

In the theme song for all of season 7, Kenny says, "Someday I'll be old enough to stick my … in Britney's butt!" (edit) Right before the aliens erase the kid's minds, they tell them to 'keep up the wars'. How are the kids going to remember this, after the aliens erase their memories? (edit) Posters on the spaceship are Gelgamek, Antares and Klingonese.

Gelgamek: The alien race that are members of the Catholic church, from "Red Hot Catholic Love."

Antares: A star that is part of the constellation Scorpius.

Klingonese: Is the language of the Klingons from the Star Trek universe. (edit) Jeff said there were 60 episodes of Punky Brewster before it was cancelled. There were actually 88. (edit) Within the episode a reference is made about 100 episodes. The production number of this indicates that this would the 100th episode that was produced by the series, but the 100th episode to air will be 3 weeks from this air date. Given reports by Matt and Trey that episodes are sometimes in still in production the morning they are supposed to be broadcast I think it would be hard to argue that this episode with the 100th production code is actually the 100th episode. (edit)

Double Allusion: The Dukes of Hazzard and Independence Day

The car chase with Chef and the boys eluding the aliens contains elements from both works. First, its a car chase, with country-tinged back up music, a narrator using colorful metaphors, and the aliens at one points use a police car in pursuit, ending up in a chicken coop a la "Dukes." It also has elements of "ID-4" as they are being chased by aliens, successfully eluding them, forcing them to crash and Chef even trash talks the aliens as Will Smith's character does in the film. (edit) Reptilicus:

The live-action Panic footage seen in this episode, where you see people running over a bridge, is taken from the infamous Danish Cult Monster/horror movie Reptilicus from 1961. (edit) Star Ocean: Til The End Of Time:

The plot of this episode bears parallel to the Square Enix game "Star Ocean: Til the End of Time." (edit) Michigan J. Frog:

When the alien, as Saddam Hussein, is wearing a top hat, swinging a cane, singing and dancing, it alludes to the former WB mascot Michigan J. Frog. (edit) Contact:

When the alien picks the form of Stan's father because it would be easier for him, it is similar to Jodie Foster's experience in the 1997 film Contact. (edit)
