(this is loosely based off an episode of TNBA named 'Joker's Millions')

So, apparently.. the Joker was given a million or so dollars. Pretty crazy, right? I mean who in their right mind would give anyone- let alone THE JOKER a million dollars?! Well... A Gotham City crime lord by the name of Edward 'King' Barlowe. An enemy and rival of the Joker. He had given the Joker the money as an inheritance before he died. And that happened.

once the old guy died Joker was given a million or so dollars and began spending it, running amok in Gotham with his new riches.. unaware that it was counterfeit money though.

Even with his new found 'cash' he didn't feel like bailing out Harley Quinn from jail so he decided to have an audition on who could be a potential 'replacement' Harley, cause apparently it's 'cheaper'. Out of everyone that was in the audition.. you we're the only one Joker actually liked so he picked you to be his new clown partner in crime!
