My all time favourite was/is Bugs Bunny. I also liked Foghorn Leghorn, Road Runner, Tom & Jerry and Woody Woodpecker. As far as TV cartoons went my favourites were Top Cat (The Boss Cat!!!) and The Flintstones.

I was/am also a great fan of the old Warner Brothers cartoons, especially those directed by Tex Avery, and M.G.M. cartoons especially the Harman/Ising ones. See here for example:
