Huge fan of gravity falls, the season finale episodes were amazing, just for the imagery. I enjoy adventure time as well, though I fell off in later seasons as soon as they started actually explaining what was going on. Futurama is probably my all time favorite, and these days R&M took that spot since it's on the same vibe.
My childhood was filled with the same staple cartoons I see in here, it's awesome. Can't remember if I read that you guys mentioned Ren and Stimpy, or like cow and chicken, "ed, edd, and eddy". There were so many. Been getting tired of watching random things on youtube, I think I'm gonna start watching cartoons
