Bullwinkle
Bullwinkle is high level. I have much respect for Bullwinkle... Probably the most "intelligent humor" in the animated programs offered at the time... particularly Mr.Peabody and Sherman. Good stuff.
Futurama. Matt Groening got away with things he could never do on The Simpsons.
Rocky & Bullwinkle, with Sherman & Mr. Peabody!
I also liked Boris and Natasha..
Droopy, roadrunner, god the devil and bob, ludwig.
Never heard of Rick and Morty. Todays cartoons would be Simpsons and South Park.
South Park, Rick and Morty, and Archer are tied. Metalocalypse is a close second
The Simpsons for me, sometimes I watch others for a while, but always return.
