I heard about this a few days ago, apparently Cartoon Network took the hint from Nickelodeon, and now they'll be showing blocks of cartoons from the 90s called "Cartoon Planet". I don't get Boomerang, either at my college or home, so I can't wait to re-watch the shows I grew up watching. Although, I never watched Toonami(do I have to hand in my geek card?), so I'll have to wait for other shows like Dexter's Lab, Cow and Chicken, etc.
I really hope it is true, and wasn't just an early April Fool's prank that was just a one day event.
