Since his retcons were for the most part Lynn's way of announcing coming attractions, this means that when he boasts about being too clever to waste his time on essay questions and too grounded to be bothered with any sort of due process of law that takes more than a commercial break to resolve, he's actually a mouthpiece for Lynn when she's being a know-nothing know-it-all. The same woman who is embarrassed by her children's dubious grades because they make her look bad is also somewhat proud of only doing well in things that interest her. We're fast approaching a strip that has an attached note that whines about how other people only do well in school to be finks to her and make her look like a lazy idiot who can't be bothered to do well in anything that bores her.
Since the Pattersons are all her, we all have to endure them screaming about being plotted against by smart people because they don't want to admit that their pea-brained sloth and arrogant refusal to think is actually the problem. We also get irritating crap about how anything that Elly can't wrap her alcohol-ravaged brain cell around is worthless.
