Are you familiar with the series Batman: Black and White? if you're not, it's an anthology book drawn in black and white and there's a story in it that presents a really freakin' good theory.

See, the Joker in many comics has been said to be undiagnosable, no one can find out what's wrong with him. And in the story, two Arkham professors are having the same problem until they find a file that reveals the person who wrote it believes the Joker is faking his mental illness so he can continue his criminal life, since if he was sane he would get the chair but if he's "insane" he gets sent to an asylum he knows how to easily escape. The professors think they've cracked the Joker but then they dismiss the whole thing just because of the fact they find out Harleen Quinzel wrote the theory.
