Sometimes I do not mind hearing the knucklehead/retarded comments made by people (not all, some are bring & insightful, 76kombi & dilgirl come to mind), because they are genuinely concerned. Nice.
This is a comic, no matter how deep it is, it is meant to appeal to a broad (read: dumb) range of people. He (not "Scott", not "SA", not whatever you attempt to associate yourself with him) is trying to reach a broad range of folks, from brilliant (not most of us) to fence posts (most of the rest of you).
Enjoy it, (mostly) keep your dumb@$$ comments to yourself (unless they are witty) & keep reading (or having someone keep reading this to you ;-)
