This is the first season in which Kenny does not die and the last season featuring Isaac Hayes (the voice of Chef) as Hayes quit the show following the backlash behind season nine's "Trapped in the Closet" episode.  This season also had a minor controversy when the Halloween episode "Hell on Earth 2006" depicted "The Crocodile Hunter's" Steve Irwin with a stingray lodged in his chest getting thrown out of Satan's Halloween party for not being in costume.  Episode 2 in this season is the last one with the Braniff Airlines logo.  All the episodes in this season were written and directed by Trey Parker.

Major Boobage: "Major Boobage" is the third episode in season 12 of the American animated television series "South Park".

Chewbacca defense: A Chewbacca defense is the name in the United States given to a legal strategy in which the aim of the argument seems to be to deliberately confuse the jury rather than to factually refute the case of the other side.  This term was used in an episode of the animated series "South Park", "Chef Aid", which premiered on October 7, 1998.  This episode satirized attorney Johnnie Cochran's closing argument defending O. J. Simpson in his murder trial.  The term has since been commonly used in describing legal cases, especially criminal ones.  The concept of disguising a flaw in one's argument by presenting large amounts of irrelevant information has previously been described as the modern-day equivalent of a "red herring" or the fallacy "ignoratio elenchi" (irrelevant conclusion).
