I was your age when I started watching. S1 and S2 are probably tamer compared to a lot of later stuff.
"With Apologies to Jesse Jackson" from S11 is the best episode of all time, IMO, and it's not inappropriate. I would have loved it at 13, 30, etc. It's a Randy episode about white fragility.
Heidi Turner was more evil than Cartman in that plotline, and although Cartman does absolutely "chaotic evil" things, he also considers himself patriotic and thinks cops are cool.
That might make him more Neutral Evil or Lawful Evil despite cooking Scott Tenerman's parents.
But I think Heidi is the chaotic evil because Mr. Mackey says "She's like Cartman but worse because she'll actually follow through."
Came here for this.
People who annoy you.
"Doubling Down" is fantastic, with Cartman finding out from Tolkien's dad that Kyle stole his girlfriend.
"White People Renovating Houses" was good.
"Sons a Witches" was the Halloween episode in that time period where the Dad Thing was getting drunk and being witches, and I thought it was funny.
I don't know if it's a specific episode but I loved S20 and S21, and I don't think most people did. I liked Heidi and I liked Cartman having a girlfriend. I wanted Heidi to stay on as a tertiary main like Wendy is for Stan but it looks like they're not going to do that.
LOL I never heard of her in my life before that.
My stomach can't handle watching the Humancentipad one, but I think they've done worse ones.
The little person who came to talk to the students about respecting differences and then makes everyone say "Hi, Fatso" to Cartman because he won't stop laughing.
Humancentipad.
The movie was such a big deal because it wasn't going to have the bleeps. They were there early on, I remember, but lessened over time, and now if you're watching them on streaming instead of cable, most seasons should be unbleeped.
