I was really hoping that the Three Jokers story was gonna be about a struggle between the 'modern' Joker, the Golden/Silver Age Joker, and the TAS Joker about who deserves to be the one, true Joker. With Cesar Romero pulling out a surprise win at the end.
And like...he wants people to think he's funny so I could see him finding a brief chaotic diversion at a kid's party worth his while if the kid wants him there
"Oh no, the Joker's crazy, he's chaos personified, he's a merciless killer"
