I could go on forever about 90's Nickelodeon shows. I grew up during this era, and I love these shows even today. I think that people mentioned most of the good ones already...All That, Keenan and Kel, Doug, Hey Arnold, Salute Your Shorts. I would put the Adventures of Pete and Pete in there too. I bought their seasons on DVD a few years ago, and I think that I like them more now than I did when I was a kid. I would definitely put Rugrats in there too. I started watching it on Netflix recently, and I forgot how awesome it was. I miss those days!
