Really? Cause theres loads of stuff from 70s and 30s that Joker does that Nicholson does, very little of Silver Age. From dancing to crimes, talking to corpses, being into art, the whole ego thing, using seemingly fun gadgets for murder, sick devotion to a woman who he wants to kill and be be with at the same time etc,
