I'm sorry, but Kathy is the world's dumbest comic strip. Not only is it multi-panel, which means it allegedly takes more effort to draw each day, but in the 30-odd-year history of the comic, there have been exactly three plots:
1) The one where Kathy worries about getting fat, and then binges in the last panel.
2) The one where Kathy worries about buying expensive clothes, and then binges in the last panel. This one actually has two sub-variants of the opening panel: the one where she's worried about spending too much money, and the one where she's worried about attracting Mr. Right. So we'll give it credit for a 2A and 2B version.
3) The one where she complains about her parents, and then acts precisely like them in the last panel.
I read Kathy about once a decade, just to make sure she's still recycling the same 3 plots - and she is. Kathy Gusewhite (or whatever her name is) should thank her lucky stars for every paycheck she's cashed after her very first one, because she sure as hell hasn't earned any of them since then.
Oh, and yeah, the commentary is much funnier than the actual Marmaduke comics themselves!
