Man, Brak rules in ways no one has ruled before or since!!!
The Brak Show isn't bad at all (as opposed to the shockingly mediocre Brak Presents the Brak Show Starring Brak that lasted all of, what, one episode), and Brak's cameos on SG:C2C are priceless (Brak conversing with Moltar about what to bring to Space Ghost's surprise birthday party is one of the pinnacles of western achievement).
But Brak's true place to shine was a series, sadly lost to the sands of time, called Cartoon Planet. Here Brak (in both his handy-dandy poses) sat around with Space Ghost and Zorak, telling random stories, singing hilarious songs that would make Weird Al jealous, reading and responding to viewer mail, and whatever else. No story, just a bunch of short skits, each funnier than the last.
Well, except for Zorak's song "Don't Send in the Clowns," which sucked. But some things about Zorak just have to suck, so he remains bitter and evil!
Anyone remember the classic "Who all here is evil? Sound off!" sketch? Or Space Ghost talking in his sleep about shopping for groceries while naked? (And the classic response to a fan letter about this, where he sang a completely unrelated song about cheese.)
Man, they just don't make shows like this anymore.
