I Miss Old Nickelodeon Shows

Man where to start with the old Nickelodeon shows? Let's see I remember watching All That, Kenan & Kel, The Amanda Show, Doug, Rugrats, Hey Arnold, Ren & Stipmy, The Angry Beavers, Double Dare 2000. There was also Jimmy Neutron, CatDog, ChalkZone, My Life as a Teenaage Robot. Early Spongebob was good. When Nickelodeon was starting to fall Avatar the Last Airbender is good, but Nick decided to hurt the Legend of Korra
