Season 1 to 10 is incredible, but everytime I tried to watch after has been awkward and forced. It's hard to take people serious who says it has been good in the last few seasons. Like people who think Rick & Morty is funny. Gonna watch this episode though.
I never really stayed with it after Season 17 or 18, not because of quality but eventually I just lost interest personally. But I would say Seasons 11-18 still had plenty of solid episodes (also the two RPG video games are really solid).
Just rewatched "I Should Never Have Gone Ziplining" last night, god I love that one.
Cartman: "We were just having a good time. You know, hanging out and making fun of Kenny's herpes."
(after this couple finally arrives who were running late which caused the tour group to have to wait 30 minutes for them)
Guy: Hey, sorry we're late! Who's ready for some fun?
Narrator: Kyle's muscles contract to force a smile, even though in his brain, Kyle is thinking, "dude, FUCK YOU."
(as Kyle is literally dying from boredom)
Kyle: Stan? Why do people say, "to make a long story short"? It doesn't make the story any shorter!
(after Kenny actually dies of boredom, and then Stan is exposed as the one who suggested ziplining as he got a free IPod Nano for signing up three other friends, so he killed Kenny, that bastard)
Stan (crying): The hardest part about it is: knowing you can't take it back! …it was a 5th generation Nano, so I can't trade it in anywhere!
