Malkin, of all places, is your go-to place for South Park fallout, including an admission from Comedy Central that they did indeed edit the motoons. They might have missed a couple though, as a matter of fact.
Of course, Comedy Central never thought to edit the depiction of Jesus covered in feces. As of yet I have heard no reports of angry rioting Christians so it looks like they dodged a bullet.
Personally, I thought the episode was funnier than most people seem to think and my highlight was the depiction of the White House press corps. They found that whole "free speech" thing very suspicious. The parallel to the NSA program was unmistakable. Sadly, the South Park version and the real thing are way too close for comfort.
Once again Parker and Stone dare to go where few others will and the country is better for it. If it weren't for them I would have never seen Sodom Hussein going love monkey on Satan or Rob Reiner stuffing donuts in his oversized cakehole.
If it weren't for them I wouldn't watch Comedy Central at all, although Mind of Mencia is getting pretty good. Did anyone see his take on immigration last night?
