Although they're both Matt Stone-Trey Parker productions, we'd never figure out how to bring "The Book of Mormon" into the "South Park" world. Fortunately, someone did. 

Simon Chong, a fan of both the musical and television show, decided to make a video combining his favorites--and it's all pretty impressive. 

With the video being an independent effort, not at all associated with either production, Chong provides a careful description of how he managed to create such a thing. For one, it took him a week to make, mostly using the animation technology (including Photoshop) that "South Park" utilizes. In addition to creating his own animation, Chong also borrowed from the recently-released video game "South Park: The Stick of Truth."
