I've always had the impression that Kevin Murphy was a Christian, even if he did lean to the left. Wishful thinking, perhaps?
I found the Joel days funnier.
I loved MST3K. It reminded me of times I and a best friend would watch movies together, and whisper cracks to each other ("Exposition!")
I'd start watching an episode, wondering how I thought it was so funny... and inside of a few minutes, I'd be laughing so hard I could scarcely breathe!
I think Kevin Murphy's character sometimes made references to church, and/or Bible studies. But then there was the occasional very-mildly risque remark; but I wondered, too.
