* The Joker was a failed comedian who only started gaining notoriety when his jokes became more... mean-spirited. Many legendary insult comics and anti-comics started out the same way.
* Many people were pissed over Moore's DisposableWoman treatment of Barbara Gordon in ''ComicBook/TheKillingJoke'', me included. [[http://lovedatjoker.livejournal.com/2402.html This review]] of the story, however, made me realize something important: ''that was what the Joker wanted''. Barbara is a young, athletic woman, and has probably done her fair share of community work (and not just as Batgirl). Joker, however, had probably hoped to make everyone in Gotham (not to mention the audience) remember her as "that poor girl that was shot by Joker", and nothing more (much like Sarah Essen Gordon). But, thanks to one John Ostrander and one Kim Yale, he failed at that - Barbara's more well-known than ever as Oracle.
* There is much to praise in Brian Bolland's art. In each panel Joker is in, he is fully capable of smirking maliciously. But when he smiles, ''[[SadClown it never reaches his eyes.]]''
* The Joker's final... [[BuffySpeak joke]]... takes on a whole other level when you realize the two mental patients are supposed to be Batman and Joker, with a level ambiguity thrown in depending on which patient is which, depending on where you stand on the SlidingScaleOfIdealismVersusCynicism:
** If you're a cynic, then the patient who jumps is the Joker, making the final plunge into madness, whilst the patient who stays is Batman, struggling to hold on to his sanity.
** If You're an idealist, then the patient who jumps is Batman, breaking free of the madness and retaining his sanity, and the patient who stays is the Joker, left to wallow in his madness.

* How is Joker's gun empty at the end? He never fires it through the entire fight and the ''only'' time he uses it through the whole book is the one bullet at Barbara.
