South Park Spoofs GOP Presidential Debates With Mysterious 'Faith Hilling' & 'Evolution' Episode

South Park is known for pushing the envelope when it comes to the show's take on pop culture, faith and politics.

That's why this week's upcoming episode, which is shrouded in mystery, is causing a mixture of anticipation and head-scratching. In an official press release describing episode 1603, we're told that the cartoon will spoof the GOP debates, while taking on the issue of evolution and "Faith Hilling."

The release reads:

The boys are consumed with a life-threatening phenomenon in an all-new episode of "South Park" titled, "Faith Hilling," premiering Wednesday, March 28 at 10:00 p.m. ET/PT on Comedy Central.

Mankind's evolution begins to accelerate at a rapid and disturbing pace. Concurrently, another species on the planet is exhibiting the same drastic development. Eventually the two species will battle to the death and "Faith Hilling" may be humanity's only hope.

Clearly, there are some questions to consider. To begin, why are the characters undergoing a bizarrely fast evolutionary rate? Also, which other "species" is experiencing "drastic development?" And above all else, what in the world is "Faith Hilling?" As for the last question, one can't help but wonder if country singer Faith Hill or religion (i.e. faith healing) will be at play. The issue of evolution, of course, will likely be a portion of the show's antic's as well.

While some of these questions are currently unanswered, viewers can be certain that they'll be in store for some humor aimed at Republican presidential candidates. A preview of the episode shows cartoon versions of Mitt Romney, Newt Gingrich, Rick Santorum and Ron Paul debating on a variety of issues. And it seems the audio actually comes from real-life statements the candidates have made.
