Same here, watched a lot of Hanna Barbera, MASK, TF, GI Joe as a kid. Years later we got Cartoon Network and such. I'm a huge fan of Ren & Stimpy, Johnny Bravo, Dexter's Laboratory, Spongebob, The Tick, Samurai Jack, Courage the Cowardly Dog and the short films of What! A! Cartoon! Brilliant stuff.
Now that I have a 5 y/o daughter and a nearly 2 y/o daughter, I watch quite a bit of Dora, Diego, Backyardigans (they're cool), Rocket Power and such.
But nothing beats Tom & Jerry and the Looney Tunes! Nothing.
