He should definitely be used for surprise gags and absurd situations that actually make people laugh too however. Like in the Gordon image above, appearing after a serious scene for a quick joke before delving into something sinister, or like in The Return of Bruce Wayne when the Joker confronts Dr. Hurt. The latter scene is especially funny to me, because of exactly how he confronts him with an absurd plan immediately after an action packed serious scene filled and a reunion of the main Batfam.
He should also be used for over the top reactions sparingly, and to throw snide subtle shade at characters. It would also be cool if they could use his plots and plans to include a lot of visual gags, even if twisted. Like when he buried that guy with his dead wife whom he had murdered years before.
He should also have a sadistic side, like in Gotham central wherein he tries to blow up a bunch of people on Christmas just to leave a bunch of kids orphaned, then he nearly collapses laughing at the thought of their joy and excitement being permanently crushed and taken away from them for their entire life, the happiest time of the year serving as a constant reminder.
