watching cartoons with my dad has always been one of my favorite ways to spend time with him. we loved:
Loony Tunes
Ren & Stimpy
Rocko’s Modern Life
The Simpsons (which imo went way downhill after season 9 or 10)
in my mind, cartoons started declining in quality/appeal around 1998 or 99, when shows like Wild Thornberries, Rocket Power, and CatDog were premiering. I hated those shows. (although Spongebob premiered in 1999, perhaps the one exception)
