This marks the first time Gerald is seen without his yarmulke. (edit) This is the second time Kenny's mouth is visible through his hood when he vomits. The first being Pinkeye. (edit) Whilst Stan, Kyle, and Butters talk to Kenny about cheesing, there is a hole in the kitchen window at Kenny's house. It's located in the exact same spot as the hole made in the season eleven episode " The List." Ironically, this bullet killed Kenny in the episode. (edit) This is the first appearance of Cartman's cat, Mr. Kitty, in 9 seasons. (edit) This marks the second Kenny-based (The first one being "Lice Capades") episode since "Best Friends Forever" in Season 9. (edit)

King: Hold! You cannot yet caress my daughter's awesome boobage.
Gerald: Huh? How come?
King: There is another suitor. (Kenny shows up)
Gerald: What? Get out of here, kid!
Kenny: Hey, f**k you! You should be the one leaving!
Gerald: You're too young for this stuff! (edit) King: I see that you're enticed by my daughter's awesome rocking tits.
Kenny: Yeahhh
King: Then bathe with my daughter in the fountain of Varnov. Appease the gods by lathering her boobs with soapy suds.
Kenny: Okay! (edit) Butters: My cousins in Florida says that the kids in their school get high off of cat pee.
Cartman: Cat pee?
Stan: That's not true, you can't get high off of cat urine, can you?
Mr. Mackey: Well, it's not actually cat urine, but male cats when they're marking their territory spray a concentrated urine to fend off other male cats, and that can get you really high. M'kay. Really, REALLY high. M'kay.
(Cuts to class staring at Mr. Mackey)
Mr Mackey: Probably shouldn't have told you that, just now. M'kay. That was probably bad. (edit) Cartman: Mr. Kitty you have to live in the attic now. Here, write a diary. (throws a diary on the ground) (edit) Butters: (About Kenny) Oh boy! He's cheesed out of his mind! (edit) Cartman: But ya know, we've all learned something, you guys. We can never persecute living beings and force them into hiding. It's wrong.
Kyle: (annoyed) And you don't see any parallel between that and anything else in history?
Cartman: Hmmm, nope. I have no idea what you're talking about Kyle. (edit) (Gerald walks up to the blonde chick)
Gerald Broflovski: I couldn't stay away cuz of your rockin tits.
(edit) Stan: Dude, we've got a big problem. Cartman says Kenny is really messed up.
Cartman: He's cheesing his f**king balls off dude.
Stan: He apparently got to all the cats Cartman has been hiding in his attic.
Kyle: What are you doing with cats in your attic, fatass?
Cartman: They're innocent victims in this! They have to hide or they'll be put to death. Something you just can't understand.. (edit) Butters: There you go.. Try some coffee Ken.
Kenny: (muffled) Hrm..
Kyle: Kenny, we need to have a serious talk.
Kenny: (muffled) Ugh, no we don't guys.
Stan: Yes we do. We're your friends dude. We're not going to let you ruin your life.
Kenny: (muffled) I'm not ruining my life, okay? Can you guys just f**kin f**k off?
Kyle: Look at yourself! You've got to lay off the cheese!
(Kenny vomits and it hits Butters)
Butters: Yeah.. That's it little buddy..just let it out. (edit) (After Kenny is woken up from tripping)
Kenny: *muffled* I wanna.. touch them. (edit) Stan: You guys! Check it out! It's Kenny. Isn't that great? He's just getting high on life.
(Kenny sniffs flowers)
Kyle: He's getting...really high on life.
(Kenny sniffs more flowers)
Cartman: Dude, he's getting super-wasted on life.
(Kenny sniffs all the flowers)
All: KENNY! (edit)

When Gerald mentions "getting high off fermenting human feces", this is a reference to the hoax hallucinogenic drug Jenkem, said to be a hallucinogenic drug composed of noxious gas formed from fermented human sewage. (edit) By turning on Closed Captioning for this episode, all of Kenny's lines are translated to English from muffled Kennyspeak. (edit) Throughout the series, it is implied that Cartman's cat Mr. Kitty is a male, but in Cat Orgy' from season 3, Kitty is a female and in heat. (edit) "Jewish Princess" was painted on the side of Gerald Broflovski's fighter plane. (edit)

Eliot Spitzer:

Gerald taking part in a practice that he was publicly fighting against, accompanied by his sorrowful speech with his wife at his side, is a reference to disgraced former New York Governor Eliot Spitzer. During his time as New York's Attorney General (1999-2006), Spitzer openly and vehemently fought against prostitution rings; in 2008, it was discovered that Spitzer himself was in fact a client of such a ring. When it was made public, he gave a speech with his obviously-annoyed wife beside him. He resigned as Governor shortly thereafter. (edit) Diary of Anne Frank:

When Cartman hides Mr. Kitty in the attic and tells him to write a diary, it is an allusion to Anne Frank, a young Jewish girl that hid in an attic with her family during the Nazi Holocaust. (edit) Heavy Metal Allusions:

The blonde chick in 'Major Boobage' is an allusion to the character of Taarna, the last of a warrior race, from 'Taarna', the final story segment of the 1981 Anthology film, Heavy Metal.

Other allusions include a segment set on board a flying fortress and a spaceship shaped like a sports car.

The song heard during Kenny and Gerald Broflovski's cat-urine induced trips is "Heavy Metal (Takin' a Ride)" by Don Felder from the film, as well as "Heavy Metal" by Sammy Hagar, which was also on the soundtrack for the original film. (edit)
