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.

Goofs

 * This episode, as the boys call Loogie to get a rose, Damien had not been selected, but was holding a rose anyway.
 * When Butters is explaining his evil eraser scheme, one of the questions says 20x9=1. The correct answer is 180
 * When The boys eliminate someone, Cartman says "Get the fudge out!" At the baseball game, Cartman says the line to Pip. However his picture still appears in the finals.
 * If you look closely in the theme, Cartman is still seen yelling at Francis and his father from Cartmanland.
 * When the boys mention that there is 20 contestants to get the position of the fourth friend, there are really 21 in the shot.
