First off, Mad published one of my gags. It was drawn by Don Martin. It was the first thing I ever submitted to them. Things went quickly downhill from there.
One Fine Morning at State Prison
I started to learn a couple of things right away; no author credit on a Don Martin bit unless it appeared on the back cover. And the fact that I had made a sale was no guarantee for future submissions.
The editors felt differently.
I did get a personal response from the editor, a letter noting my lack of professionalism and a request that I never send them any material again. Obviously, we had conflicting concepts of "professionalism."
Yeah, so I was "banned" from submitting to MAD. It hurt. I know, I know, it was a stupid move on my part, but I was really angered by it. There are times I'm simply tired of submitting my best, making a connection and then finding out that I'm back at square one. It was just a Groundhog Day of specs and cold submissions and MAD received my wrath.
Naturally I didn't submit again...for a while...
