Looney Tunes! My favorites:
Bugs Bunny and Elmer Fudd
Daffy Duck and Porky Pig (I did not like Bugs Bunny and Daffy Duck cartoons. They were funny but the old school goofy Daffy was the best.)
Foghorn Leghorn and the dog that had no name for some reason
Roadrunner and Coyote
Pepe Le Pew and the cat he sexually assaulted in every episode
I also loved the Ninja Turtles, Scooby Doo, Tom and Jerry, and Johnny Bravo just to name a few.
