Boy, CN has been blowing through these episodes recently just like they have with Adventure Time and Uncle Grandpa.
The episode with the school being taken over by a fast food chain seems to be a pretty harsh commentary of cash-strapped schools across America who are so desperate for funds that they would need to partner up with corporate interests, a real-life example I remember about being one school whose buses were plastered with advertising to score some extra money. (spoiler: Of course, it was revealed that it was really all just part of Clarence's school project.)
And I liked the episode that followed it with Clarence and Sumo engaged in a get-rich-quick scheme, particularly for Chad and Sumo's dad's interactions with one another.
And the one with Clarence visiting an injured Belson at the hospital and annoying the crap out of him was more cringe-worthy than anything (spoiler: though it was kind of a karmic injury, plus Clarence does get injured in the end, making it a bit less cringe-worthy.).
