I still remember when I first had CN, back in 1994. Each morning, before school, they would show old stuff like Yogi Bear, HuckIeberry Hound, Snagglepuss, Augie Doggie, etc. I'd come home from school everyday, and watch more old cartoons like Space Ghost, Herculoids, Thundarr the Barbarian, that Godzilla cartoon from the '70s, G-Force (aka "Gatchaman"), etc. I also remember watching cartoons like The Jetsons and the Flintstones after dinnertime.
There was also this one April fools joke they pulled back in 1995? 1996? where they showed the same Screwy Squirrel short over-and-over, in a loop, all day long. That shit pissed me off.
