Favorite Old-School Nickelodeon Cartoon

[Punishment1o1]

So I come home from work tonight and my sister has it on TeenNick and what's on?! None of than Rocko's Modern Life. I have never seen it on TeenNick before. It's always been the likes of Hey Arnold! Doug. As well as some of the other live-action shows. Anyways, watching these shows makes me realize how much I miss the old Nick and these cartoons. Nickelodeon these days seems to be full of shows about actors/actresses trying to be musicians trying to be actors/actresses. It isn't even fun to watch. That brings me to this poll, what it you your favorite old-school Nickelodeon cartoon? While I always enjoyed most of the old cartoons, I was always partial to Rugrats and Doug. To, me they were the most entertaining. Btw, I deliberately left out the live-action shows as it would have made the list too long. Maybe I'll start another poll for that. Anyways, now it's your turn? What's your favorite old-school Nick cartoon?
