Well I put rugrats since I've been watching it the longest... but aaagh real monsters, catdog, ren & stimpy, rockos modern life & the wild thornberrys all have a special place in my heart Aah nostalgia!
Ah! You mentioned KaBlam! I miss that one. It was soo random!
I picked Rugrats. It was hard for me to decide because the only one I didn't like was Ahh!! Real Monsters. I used to watch it but the characters totally creeped me out, so I never really liked it. But Rugrats, oooohhhhh.....I can't get enough of that. I'm just glad some of the ones you mentioned are now on Netflix so I can instant watch to my leisure.
