As a child, midget gem variety:
Atom Ant, Mr Magoo, Twizzle, the Woodentops, Bill and Ben, Jimxy, Deputy Dawg and Quick Draw McGraw (sp?), the Woody Woodpecker Show, which I never found funny.
Slightly later, there were Crystal Tips, MM &M, R&C, Ivor, Noggin, all the Trumpton stuff, Flintstones, Jetsons, and I remember a pile of truly crap H-B stuff. We had moved to the Far East for a while, so I got exposed to a lot of Japanese stuff such as Prince Planet.
Quite a bit later, Tom and Jerry, but ONLY the Quimby stuff; my father made a point of saying 'Good Old Fred' each time. Droopy, who is a true original. Scooby-Doo. A lot of the Disney stuff quite late, due to the stay abroad.
Then....as an adult, allegedly: Bugs and his crew (favourite line: Duh, you can't fool me, I'm a moron!) and then Ren and Stimpy (I have nicknamed a colleague Stimpy), Duckman, and the wonderful Monkey Dust.
