The Onion also continues to kill it. IDK what this even means
Basically it's been done to death on South Park and it's not that funny anymore within SP's satirical style. What they mean is the reality of this administration is too ridiculous that there's no room for anything insightful or interesting to be said about it in the context of the show(which, keep in mind, is supposed to be about a little Colorado town and its schoolkids). Also like I started with, they've already focused a whole season or so on Trump.. never before have they focused on a presidential candidate or really any person/celebrity for more than an episode or two, so I really think they've covered their bases and proven their point on this matter.
Tbh I'm sick of Trump on South Park, so this is welcome news.
