Cartman states that AIDS isn't funny even though AIDS had been officially declared funny in the episode "Jared Has Aides".
This episode may have been the creators' protest that many pharmaceutical companies have cut funding to research AIDS treatments, and how if a cure for AIDS was discovered then it would cost too much for people in places such as Africa (where AIDS is a major problem), who would not be able to afford the cure.
When Kyle tears the Mel Gibson poster apart, he was screaming in rage, which was only heard in the digital release of the episode and not on the original Comedy Central broadcast.
This episode features a new opening sequence. It begins with the camera zooming out of Stan's eye as the characters fall into place like in the original version. Then various clips from past episodes are played out like in the Season 6 - 11 opening. As the boys sing their lines, they move about across the screen while minimized clips are played out. The crowd scene is also redesigned and includes future atheists, The Lollipop King, and Jesse Jackson amongst others. The theme music remains the same as the one introduced in "Make Love, Not Warcraft".
As Kyle and Cartman enter the airport, a voice over the loudspeaker says "The white zone is for loading and unloading..." This is a reference to the opening scene of "Airplane!". The same line is also used in "Toy Story 2" when the toys arrive at the airport to save Woody from going to Japan.
In the episode "Red Sleigh Down", Kyle's cousin Kyle said if Cartman cured cancer and AIDS, he would still owe Santa two presents.
Cartman acknowledges how he has broken into Kyle's house many times before, something which he has not noted before despite having been seen numerous times, including "Casa Bonita".
Cartman squirts his blood into Kyle's mouth. Blood transfusions normally cause serious problems when not crossmatched, but Cartman has the same blood type as Kyle, as stated in "Cherokee Hair Tampons".
Also from "Cherokee Hair Tampons", Kyle did actually have a transfusion of sorts - he is currently using one of Cartman's kidneys.
Cartman's Xbox also reappears, having been seen previously in "Tsst".
Clyde Frog is also seen, having his head ripped off by an enraged Kyle, once again inferring Cartman's love of his stuffed toys.
A flag with a picture of a cow on it and the words "Cow Days" appears in Cartman's room. This is a reference to the South Park festival and episode entitled "Cow Days".
