In no particular order, mine are:
Pink Panther but only the original DePatie-Freleng version from the mid-60s onwards. I've relatively recently come to appreciate the Inspector sequences. Never like the Ant and The Aardvark.
Daffy Duck, Foghorn Leghorn, Tweety and Sylvester, Roadrunner and Wyle E. Coyote. And Porky Pig. Bugs Bunny was too much of a smartarse for my taste.
Tom and Jerry but only the Fred Quimby productions. Everything else couldn't cut it.
Dangermouse had broad appeal. Slapstick and more sophisticated humour.
Will 'O The Wisp was slightly bonkers.
I always used to watch Marine Boy and Battle of The Planets..planets..planets. I didn't realise back in the 70s and 80s that both were Japanese.
