Arkham Asylum: A Serious House on Serious Earth/Funny


 * Joker slapping Batman's ass. It's one of the few, if only, genuinely hilarious moments in the book.
 * However, the annotated script says that this particular version of Batman was envisaged as being extremely neurotic and sexually dysfunctional. Consequently, this was meant to be a moment where Batman feels extremely violated, and the Joker shows that he has seen straight through Batman's armour and knows one of his major weaknesses.
