Kind of a strange april fools joke for Adult Swim considering most of their pranks make the april 1st block unwatchable. But it's on, and showing all the classic shows.
I wonder how they managed to pull it off considering they lost the liscenses to broadcast many of these shows ages ago. DragonBall Z, for example, is now on Nick. I'm just saying... be grateful, it has probably been a lot of work behind the scenes to arrange this airing.
