Ok this is a thread I can get behind.
For Cartoon Network, there was a lot of shows I enjoyed watching, Amazing World of Gumball, Regular Show, Ben 10, TTG, Foster's home for imaginary friends, Chowder, Flapjack, My Gym partner is a monkey. There was also old cartoons that aired in the early early morning, right after Adult Swim would end like Dexter's Lab, Samurai Jack, Courage the Cowardly Dog, Ed, Edd, 'n Eddy, Codename: Kids Next Door. For me, I would have to say the one I enjoyed the most would probably be Regular Show or Amazing World of Gumball (normie choice, I know.)
For Adult swim, it's either Family Guy, American Dad, Aqua Team Hunger Force, King of the Hill, Squidbillies, Futurerama, Harvey Birdman at law, The Brak show. All very funny shows but Futurama, Family Guy, American Dad, and King of the Hill are kino.
