Last week's "Let Go, Let Gov" was brilliant IMHO. For me, it's a classic I'll definitely re-watch. Nailed the hypocrisy with many Americans who freak out about the NSA Verizon Wireless story yet blast so much of their lives online. And it's freaking hilarious how they do it, which goes to whole point that when South Park is on its game these days, it's the funniest show on TV.
As long as this season is at that level or higher, it's going to be a great "classic" season of South Park. And yes, to be fair, I'll take anything to continue to wash the taste out of my mouth of that episode where it turns out the City Wok guy is the multiple personality disorder dude.
