that's a bit like saying KND has a "stupid" premise because there's no way an elaborate underground society of kids could escape notice, and there's also no way kids could defeat adults with toy-based weapons and so on. but the cartoon breaks from logic and reality on purpose and is better for it. and there is authenticity because it is a creative exaggeration of kids not understanding the adult world and feeling oppressed by it.
the joke in My Gym Partner's a Long Ass Title is a satirical poke at the school system, plus a creative exaggeration of "having to abruptly leave all your friends and go to a wildly different school because of something arbitrary like zoning." they could have come up with a different reason to send him to the school but "some retard made a typo" works and is also amusing. It's a "wackier" type of show, it's perfectly fine to do things just because they're amusing in a show where that's the priority.
the strength of the "cartoon" medium is that you aren't bound by reality, physics, or logic. you're free to do literally anything, especially stupid or silly or surreal things that aren't possible outside of the medium of animation. a ridiculous or even dumb premise isn't a bad thing.
you have to at least give something a fair shake before you can analyze how it does or doesnt hit the mark. don't complain about how it makes no sense for spongebob to be a fry cook if he lives underwater, or some banal shit like that which is deliberately missing the point of cartoons in general (they aren't bound by the limitations of reality).
