Yes, Toonami has aired comedy series before, but almost all attempts at doing so were divisive at best. The only one that was really mostly successful was Space Dandy, and that show was given an 11:30 PM world premiere (at least until the original Attack on Titan started airing, relegating it to 12:30 AM), with the promos highlighting the fact that it was directed and produced by Shinichiro Watanabe and Studio Bones.

I'll admit that I haven't seen much of Attack on Titan: Junior High (is there even any action in it? At least Bobobo-bo Bo-bobo can be considered an action-comedy show), but Toonami has made it clear that they don't want to stray too far from airing action shows.
