Next Friday, March 30th, at 8pm eastern/7pm central, Cartoon Network (not AS) will be airing an hour long special entitled “Best of Cartoon Network”. It’s the network’s 20th anniversary this year (October 1st, to be exact!) so they’ll be showing some of their favorites, some of their best cartoons from the past 20 years of Cartoon Network history. Whether or not this is a one-off special or part of a series of specials I’m unsure, mostly because I’ve seen no other information about this and I can’t get my program guide to load the following Friday’s program info, but I would assume this is a one-time anniversary special.

The special isn’t going to stick to only the classics, though. We’ll see more than just old ‘toons we’ve seen before. We’ll see some new content, too, and it’s new content I’m sure Adult Swim fans will be interested in.

Andy Merrill, voice of Brak, ATHF plutonian Oglethorpe, and writer on Space Ghost Coast to Coast, Cartoon Planet, and more, took to Twitter today to talk a bit about a little surprise that’ll be a part of the CN special. A surprise he then unveiled on his own on the site:

New Cartoon Planet stuff, y’all. New Cartoon Planet stuff.

Of course, in recent years we’ve seen newer Space Ghost Coast to Coast bits on Adult Swim, mostly for promotions (the network’s Avatar promotions wherein Tad interviewed Zoe Saldana), and for April Fools festivities (SG’s guest being Tommy Wiseau during an airing of The Room). But we haven’t seen anything closer to Cartoon Planet, Coast to Coast’s more kid-friendly counterpart.

Now we will, March 30th, as Brak and Zorak team up for the first time since The Brak Show to bring us some classic Cartoon Network goodies. Tune in next Friday at 8pm EST, you’ll most likely not want to miss this. It’s not something that happens often.

UPDATE 3/27/12:

So, turns out this isn’t a one-off, but a weekly thing. Two weeks long, at least. The ToonZone forum (and commenter on this post Mastercylnder) points out that the Adult Swim backdoor schedule actually has the special(s) listed along with the episodes of shows that will be in each episode. The two hours look like this:

March 30th:
Cow and Chicken – Happy Meat
The Powerpuff Girls – Meet the Beat Alls
Fosters Home For Imaginary Friends – Sight for Sore Eyes
Johnny Bravo – Johnny Bravo Meets Adam West
Dexter’s Laboratory – Star Spangled Sidekicks

April 6th:
Camp Lazlo – Campers All Pull Pants
Chowder – Chowder’s Girlfriend
Ed, Edd n Eddy – Honor Thy Ed
The Grim Adventures of Billy and Mandy – Chocolate Sailor

That’s what you’ll be seeing amongst the new Brak & Zorak bits in both hours of Best Of on CN. Starts Friday! Watch! DVR! Etc!
