I kinda agree, it does have good jokes in some episodes. But most of the lessons they teach aren't ideal at all. The school episode you mentioned was, I think, the most serious episode when it comes to its message. The half of the other episodes are literally saying "Have a lot of money instead of friends" "Christmas is all about presents" "Girls are weak" "It's better to be stupid than smart" I mean, that's worrying considering there's a lot of kids watching it. They shouldn't consider kids like idiots.... If it doesn't get cancelled (which I doubt cause it's airing so much) then at least make it a bit more serious, with decent lessons for children.
However, I respect your opinion if you like this show you are free to obviously. That's just how I feel about it.
