I immediately had a crude response to this, but didn't share it.
Of course, I know there is a Church Sign generator out there on the web, since my boss told me about it. The signs remind me of the collection of Jim Nabors records my father has that I used to listen to on a regular basis. Yes, Gomer Pyle is a deeply religious man. I think he meant well with this aspect of his career, but I'm not sure how much respect he garnered. I loved to hear his voice belting out "Go Tell it On the Mountain" on my dad's Sears and Roebuck stereo.
