** It's also possible that, even though it doesn't really fit Joker's character, profit was indeed the real goal, considering how in just a few years, he'll become broke to the point of having not even acid in his flower. Perhaps his goal to obtain money from the Joker Fish was to further fund his operations (i.e. game with Batman) and maintain his henchmen and functioning equipment. Perhaps Joker's plan in this episode foreshadows the events of "World's Finest"?

* AlternativeCharacterInterpretation: Joker’s motivation. It’s not made clear if he legitimately thought he could copyright fish (since he might be a criminal mastermind but not necessarily well-versed in copyright laws, plus he’s [[CaptainObvious nuttier than a fruitcake]] and prone to InsaneTrollLogic) or if his scheme was just an excuse to try and kill people and to flush out his favorite [[Characters/BatmanTheCharacter sparring partner]], [[TakeAThirdOption or if it started as the former but then turned into the latter]].

*** And even harsher, Batman succumbing to the Joker Venom in an alternate universe is essentially the origin story for [[ComicBook/DarkKnightsMetal The Batman Who Laughs]].

* FunnyAneurysmMoment: This line from Harvey Bullock to Harley about the Joker, which turns out to be even more [[MadLove horribly true]] than he could have ever thought.
-->'''Harvey Bullock:''' Come on, he was a demented, abusive, psychotic maniac.
* HarsherInHindsight: Before TheReveal, it looked as though Batman was affected by the Joker venom (via cat scratch). He ends up getting affected for real in ''WesternAnimation/BatmanBeyondReturnOfTheJoker''.
