Using two kinds of animation in one show

I must apologize to those who don't like reading about South Park constantly, but to be honest, that show directly relates to what we talk about and there are also several examples you can pull from their episodes to use as examples. I'm going to use them again, as an example to say that using two different kinds of animation in one animated show, or any other piece of animated work, should be done more often in today's world of animation.

I'm sure that a lot of people would disagree with me when I say this because it doesn't exactly fit "traditional" animation. However, I present to you the South Park episode, "Make Love, Not Warcraft."

Here is a link to a faster example for you, it shows you within 30 seconds the different kinds of animation it uses.

This is a perfect example of how two kinds of animation works. Watch that episode, or at least the other video I provided a link for to understand the point of the story, and try telling me that that episode could have been as good as it is if it didn't use Blizzard's animation technology. I can assure you that it wouldn't have worked out as well. As a side note, that is actually Blizzards animation technology. When South Park had the show idea, they contacted Blizzard and Blizzard was nice enough to do the animation for them, which is why you always see Blizzards' logo in the episode.

This topic also reminds me of a particular Family Guy episode (I can't remember the name) where, at the end of the episode, Peter is talking a bunch a garbage towards FOX, and right before he walks away he says something like, "It's not like they can take our budget away" and as he walks away, Peter turns into this blocky character that can't walk and he just wobbles of the screen.
