Also, I've seen the episode of Sealab where they each form their own country at least 4 times now, but the Five Jew Bankers only once. Is it odd timing on my part or did Adult Swim actually find something too offensive to air again?
No, they didn't cancel AD and FG... They have commercials of them. They did however, sell the rights to AS to play reruns of AD. CN is getting the rights to the rejected Boondocks from Fox though.
