Even though I still think "Ball of Revenge" is an amazing episode, the more I think about it, in hindsight, it feels more like a fanfic than an episode, if only because it seems very much like the kind of fic a fan would write: bringing many of the show's villains together against Courage in a single battle? Not to mention other little surprises, like the Duck Brothers making a cameo? Not to mention Eustace's nastiness seemed to really be cranked up beyond 11 in that he went this far to see that Courage was killed, and didn't even care if Muriel was used as bait to lure him to his demise, despite previous episodes showing that, deep down, he did actually care about Muriel and her safety.
