Want do you want to show me? I didn't tell that there wasn't stupid gags and jokes in previous seasons, but they was much better than the jokes from S9b. In addition, you showed me only moments from seasons 5-7
You said something along the lines that the show got stupider starting with Lost in Bikini Bottom, which doesn't include 5-7. That implies that they somehow did them better in those seasons, which I find crazy. You don't really explain why they don't work now but the series has been similarly stupid since Help Wanted, and for the most that's what makes it funny.
Oh and trust me there are stupid moments just like newer episodes in seasons 1-4 imo. I just chose infamous stupid-moments that are dumb in a bad way. I don't want to derail this topic so this will be my last response but re-watching 1-4 I can find an equal amount of weird and zany moments imo.
