"Yo, Toonami Faithful... Thanks for tuning in. Hope it kicked in some happy memories and kicked off a happy April! As you (hopefully) know, bringing Toonami back isn't up to me. I'm just a voice guy. Many of you want to know how to make your voices heard. Maybe start here...
http://www.cartoonnetwork.com/feedback/ Go to "programming" then "Toonami" Love you guys from the bottom of my servos."
So I went to their feedback page, went to programming, and lo and behold THERE IS A TOONAMI CATEGORY. They may actually be serious.
And while it's unlikely that they'd bring the block back, let's discuss this for fun: what kind of shows could they put on there? I know that we'd like some of the old school stuff, but what about new shows?
