Bring back to Cartoon Network:
Old school Looney Tunes - Recently, for some holiday (new years?) CN played a marathon of the old cartoons. Wile E. Coyote, Bugs Bunny, Daffy Duck, the good stuff. I called my girlfriend to cancel the date tonight, she asked why, I told her, she came over. WE GOT GROWN FRIENDS TO COME OVER AND WATCH CARTOONS. I actually laughed, laughed, while watching Cartoon Network. That hasn't happened since Adult Swim got rid of Futurama.
Old school Superhero Cartoons - Batman TAS, Superman TAS, hell, Batman Beyond, the Justice League, Christ, I'll go with Static Shock. These were all bearable, and I'd watch them occasionally, and they actually made good kids instead of this scary Japanese bullshit.
Toonami - Thundercats. Thundercats. Thundercats....HOOOOOOOOOOOOOOOOOOOOOO. Nothing else needs be said.
Tom & Jerry - I'm pretty sure this is played during lunch. Play it more.
I realize that the Boom channel exists, but it generally has the SUPER old cartoons, not just the good ones.
