Cartman uses fetal cells to clone Shakey's
I think in the end, they demonstrated that the fetal stem-cell movement is driven by profit as much as by human concern. Obseve that Cartman was just trying to use them for his personal gain all along, and apparently had crocodile tears for Kenny.
Yes, but that was also the "Kenny Dies. For Real" episode, which was why they were doing the over the top with the drama. They were going for the "Movie of Week" vibe that you often see on Lifetime. Plus, it's impossible to find a Shakey's in Colorado, which is why cloning them is a good thing.
(And the Chris Reeves episode came two years later, so they didn't do this one as penance.)
"dangus, you're bustin' my balls here. I'm just like these fetuses, dangus, I wasn't born last night either."
