Professor Chaos/Trivia


 * There is a hidden visitor standing in the yeti log ride.
 * The song that Towelie tries to play on guitar at the talent show, is Led Zeppelin's Stairway to Heaven
 * On the last page Butters reads says "Flying Frogs Put This Years Crops In Danger". Possibly, it might be a reference to "It Hits the Fan".
 * Distraught, Butters wanders home and laments at his bedroom window, recalling the many things he did for the boys, such as buying tampons for them and going on "Maury Povich" with balls on his chin for them.
 * The next day, Stan, Kyle, and Cartman hold a contest reminiscent of "The Bachelor" in order to choose a new friend to take Kenny's place. Many children show up, as well as Towelie, and also children who had only appeared in one episode, such as Loogie and Damien.
 * On the wall of the room in the beginning there is a "Cow Days" banner and a stuffed panda which looks like Sexual Harassment Panda.
 * Damien has only appeared in "Damien" and South Park: Bigger, Longer & Uncut at the time, but is seen in the background as a candidate to be the boys' new best friend.
 * The scene where Butters is making his Professor Chaos costume is a reference to a scene from Batman Returns.
 * This episode parodies "The Bachelor" and "The Bachelorette".
 * Cartman breaks the fourth wall when referring to Dog Poo as a "prop".
 * The music at parts of the friend choosing game might be a reference to the music of Friends

 * At the baseball game, Cartman tells Pip to leave. However his picture still appears in the finals.

 * When they are handing out roses for the final 6, it is shown when Jimmy is getting his rose that Craig is clearly holding a rose in his hand, but didn't get nominated.
