Kenny and Kyle don't have large speaking roles in this episode, despite Kyle's often-shown disdain for Cartman. Kyle only has one line, and Kenny has none.
This episode aired in October, which in the United States is Breast Cancer Awareness Month.
The fight scene between Cartman and Wendy, as well as the music, is a direct reference to the final boxing match from the film Snatch.
After the fight, Wendy sits on the ground next to Cartman who lies face down in blood. Mr. Mackey approaches and says "Wendy?" to which she replies "I'm finished". This is a reference to the final scene of the film There Will Be Blood.
When Liane and Eric are at the Testaburger's house he is lying and talking to his mother in a way reminiscent to the way Ferris Bueller does in the film "Ferris Bueller's Day Off". "Cartman: Okay Mommy. Ma ma ma ma."
Despite the events in "The List", Wendy and Bebe are shown to once again be friends in this episode.
This is the second episode since "The List" to reference Stan and Wendy's rekindled relationship, the first being "Super Fun Time". Cartman references their relationship, saying "You're my bro, and she's your bitch." Pete also mentions their relationship.
Cartman has been involved in a fight before, in "With Apologies to Jesse Jackson", where he managed to fight his opponent pretty well, whereas in this fight he didn't.
This is Tweek's final regular appearance in Mr. Garrison's class.
