Amazing work, Carl! Whoever you are!
I also wrapped up S3 recently. I'm finding that the show is not always riotously funny, but I'm not sure it's necessarily trying to be, and I still get a lot of pleasure out of enjoying the commentary, character development and just plain sheer imaginativeness that it continues to offer. As shows age they always risk getting stale, and a concept like R&M's might have some built-in shelf life already, but I don't know what it is and we passed it yet.
The fact that Pickle Rick has entered the zeitgeist so quickly and fully tells you how relevant and good the show remains. I find that encouraging.
