 * In a pan shot of the cafeteria, a voice identical to Kyle's Cousin, Kyle Schwartz can be heard, talking about his bad gas, coming from a Jewish kid with stringy black hair, which is not how Kyle Schwartz looks like. Cousin Kyle would not be introduced until several seasons in the future.


 * Two Hasidic boys can be seen in the cafeteria, one of which resembles Jason, who was formally introduced in season 6. They would make reappearance in An Elephant Makes Love to a Pig, when a deleted scene from the original pilot wound up recycled.

Pop-Culture References

 * When Officer Barbrady investigates the mutilated cattle, the farmer mentions seeing black CIA and army helicopters in the area. Black or unmarked military helicopters (usually belonging to some US government department) are common trademarks of UFO and alien abduction lore, that suggest that the UFO phenomenon is being covered up by the government.


 * When Stan sees Wendy in the cafeteria, his smile is similar to Charlie Brown's smile when he sees the Little Red Haired Girl in Peanuts.


 * I Love to Singa, the song that plays when Cartman and Officer Barbrady are being put under alien control, is originally from a Tex Avery Merrie Melodies short. The song was written by Harold Arlen and E.Y. Harburg.


 * Cartman says that the crop circle looks like Tom Selleck, the actor best known for playing the character Thomas Magnum in the show Magnum P.I.
 * When seeing Cartman farting fire, Wendy says that he's "just like Rudolph!", referring to Rudolph the Red Nosed Reindeer the popular Christmas character that had a nose that would shine red light.


 * When Chef is calling out to the aliens to visit him, he asks them to hurry up because the TV show "Sanford and Son" is about to come on.


 * To goad Ike into jumping out of the alien's UFO, Kyle tells him to do an impersonation of David Caruso's career. At the time this episode was made, David Caruso had just recently ended an unsuccessful stint on the TV series "NYPD Blue."
 * At the end of the episode, Cartman claims that actor Scott Baio, who got his claim to fame playing Chachi on the TV series "Joanie Loves Chachi", was aboard the UFO and gave him pink eye.

Continuity

 * Half of the scene which takes place in cafeteria was cut and later used in An Elephant Makes Love to a Pig.


 * When Wendy remembers the times when Stan throws up in front of her in Tom's Rhinoplasty, clips from previous episodes are shown, including the one from this episode.

 * Reused clip from this episode appears in The South Park Clipshow (a.k.a. "City on the Edge of Forever").
 * In the end of "Cow Days", Cartman comes to his friends, Stan and Kyle, to tell them about his 'dream' until realizing that it was real events when he dressed like a prostitute. It is the reminder of this episode.
 * In "Free Hat", Trey and Matt made fun of South Park, promising that they'll redo the pilot episode... again.
 * In a later episode, "Canceled", the first part of this episode is redone, with harsher language and more elaborate animation (such as Ike getting kicked and Cartman getting dragged down the alien hallway), with the boys thinking that they are experiencing déjà vu. Cartman also mentions about his 5th visit in the outer space (two of them was in this episode)

Kenny's Death
The Visitors' UFO blasts Kenny after Kyle throws a rock at it, and Kenny is flung into the road. He survives, but a herd of cows run him over. He survives that, but Officer Barbrady runs him over with his police car and kills him. The boys later mess with Kenny's bloodied corpse, with Stan tapping it with a stick while Kyle removes his head, trying to convince Cartman that he's dead. Rats then come and start eating Kenny. In the unaired version, Kyle says "Rats!" when he and Stan leave the corpse.

Goofs

I don't think I have to fart anymore tonight" And "I don't wanna", and in the background, it is seen small stars, but in the third, when he says "Ok... that does it", you see a big star between the small.
