Hey Arnold! was the sh*t. Doug was cool too. Rugrats was cool as well, but that All Grown Up crap was a disaster. Rocket Power was cool sometimes as well. Then there's Bobby's World. I watched that show every morning before school as a kid.

Thank you all for making me feel extremely old. :p: I watched stuff like Superfriends and Fat Albert growing up. You gotta love Aquaman surfing on the dolphins in this clip:

For me Rugrats died when they introduced Dill, but it got even worse when they added that asian baby and that babysitter voiced by Amanda Bynes. But yeah, All Grown Up was the final nail in the coffin. They took a great kids show and raped it to death.

Early Spongebob is also great. But the later episodes that have come out in the last two years or so, maybe longer, well they've all sucked. Spongebob is just annoying now.

Tom&Jerry
Pokemon
a lot of overdubbed Anime
and last but not least ...
Teenage Mutant Ninja Turtles!!

No love for the Jackie Chan Adventures?

I remember back in like 4th the first anime I was ever into was Hamtaro. I remember playing the game on gameboy as well.
