Uhhh let's see.
I love the Simpsons. I don't get why people hate the early 2000's ones? Especially since they're a lot more relevant now. People may say they're edgy but to me, the original 8 seasons got away with a lot of crazier stuff.
I'm a huge Looney Tunes fan. Something about them rotating characters appeals to me. I think people should look at that show if they want to make their humor timeless. Daffy Duck is also my favorite cartoon character ever. By the way, did you know Bugs Bunny was a Daffy Duck knock-off? They even reference this in Back in Action (which was a wonderful character deconstruction). "Oh I'm a fan of your earlier work...". I'm obsessed with the fact that one of the reasons Daffy became jaded was because both him and Bugs were essentially the same character, but HE became the butt of the joke. Had things played out differently, Bugs would've been like Daffy and Daffy would've been like Bugs in that Duck, Rabbit, Duck short.
Jojo's Bizarre Adventure. This is the show where it makes me go "I didn't know a writer could do that". Whenever I talk about it, I just like bringing up small little things from that show because the author put SO MUCH care into every little decision.
The Disastrous Life of Saki K. This is probably the only Japanese show I've seen that does awkward humor really well. It feels like an American wrote it.
Smiling Friends, Assassination Classroom, Batman: The Animated Series, and Boondocks. Boondocks is like the only show I'd watch that goes into political issues.
