I'm surprised nobody's mentioned The Critic yet. It was a good show that was screwed over by two networks. Another one is Dilbert, which was based on the comic strip. I think Scott Adams was less involved with it than the strip which made it better (plus he wasn't as insane back then).
A buddy of mine owned a video game store that I worked at for a bit. The pay was crappy and the hours were unstable and random, but I do miss working there.
Oh I remember this. Turns out it was Maggie who shot Mr. Burns
