I meant for King of the Hill coming to Adult Swim. Although I have no idea which came first in that area.
Oh in that case, Squidbillies might have come first. Though, they're really quite different shows, I find it hard to believe that Squidbillies would get people to want King of the Hill. I mean, Squidbillies at least tries to squeeze in one joke per episode, a quota too high for even an entire season of King of the Hill.
