Cherokee Hair Tampons/Trivia

Trivia

 * Comedian duo "Cheech and Chong" guest-star in this episode. Although their voices were recorded separately, this episode was the first time they ever did anything together as a duo in several years, after they had broken up. A few years later, they reunited.
 * In the Comedy Central promos for this episode, Cartman says that he plans on making Britney Spears his love slave with the ten million he gets for Kyle's kidney. In the actual episode, Cartman says that what he intends to do with the money isn't an issue (because all that matters is that Stan gets the money before Kyle dies).
 * When Cartman refuses to donate a kidney to Kyle, he sings "no" to the tune of "Comedy Tonight" from A Funny Thing Happened on the Way to the Forum.
 * Right before Kenny dies he says a few lines to Stan in anger. Though the lines are muffled as always they can be made out to be "You don't seem to care when I Die" and a variation of Cartman's line "That’s it I have had enough of this bullshit! Screw you guys! I'm going home!" He also does the hand gestures Cartman does and walks away to his death while Stan just cries over Kyle, putting some truth into his first line.
 * When Miss Information visits Kyle, he throws up on the floor and she says it is simply the toxins leaving his body. Stan disagrees and says it's the bean with bacon soup Kyle ate half an hour earlier. Kyle is Jewish, and Jews can't eat bacon.

Continuity

 * In this episode we learn that both Kyle and Cartman's blood type are AB Negative.
 * In this episode they reveal that Kyle is diabetic.
 * This episode marks the second appearance of Cartman's pet pig Fluffy. The only other time Fluffy appeared was in the season 1 episode "An Elephant Makes Love to a Pig"

Kenny's Death

 * He is crushed by a piano as he is walking away from Stan, who has just offended him by his crying over Kyle's impending death whilst not caring about all of his own, somewhat more numerous deaths.

Goofs

 * During typing, Mr. Garrison's hand in use disappears when he starts typing each button.
