The decision to do an episode with the theme of atheism was finalized when Penn Jillette emailed Parker and Stone expressing his disappointment in finding out that they are not atheists themselves. Parker and Stone's religion was questioned in an interview, which prompted Jillette's email. It was assumed that they were atheists, so in the interview they clarified that they were not strictly atheists. While this was happening, Parker was anticipating the release of the Nintendo Wii, so it was decided that this scenario would also be a theme in the episode.
