Sometime in December, I think, but if I recall there wasn't a whole lot of in-depth analysis about it.

For specific questions, you could always try the horse's mouth. There's a very brief description of LDS beliefs there, and if you have any questions you could bring them up here or use the e-mail form on the site.

I did a quick Google for that episode, and I didn't find any intelligent discussion about it (i.e. discussion by actual Mormons or even people who can do anything besides echo classic rumors and provide links to anti-Mormon web sites). A whole lot of assumptions about Mormons going to start staging protests about the episode, but no actual reports. ::shrug::
