Is the episode on south park "all about the mormons" factual? —yeaaa

I saw this episode today. It said he translated the testament out of a hat, and then someone lost that translation so he read an entirely different testament out of a hat which is now the book of mormon. Is this true?

It's been a long while since I've seen it, but I don't remember anything in that episode that seemed wildly inaccurate. It was basically like watching the LDS church's own "First Vision" proselyting video, but with "dum-dum-dum-dum-dum" background music. I do remember that the South Park episode implicates Lucy Harris ("smart-smart-smart-smart-smart") in the disappearance of the first 116 pages, and that is purely conjecture though widely believed.
