The episode begins with Batman
chasing The Joker
in an electronics fair. During the chase, Joker and Harley Quinn have difficulties like running out of bullets and their car not having any gas. As soon as Batman and Batgirl catches up to them, Joker made an escape with the only parachute
. This outrages Harley as she gets sent to Arkham.
Arriving at his apartment, Joker is shown to have money problems, including late for rent. He gets the news that he inherited millions from a recently deceased mob boss King Barlowe, much to his excitement. He begins living large, tossing money left and right, even hiring a replacement Harley (with the real Harley getting even more
enraged when she hears about it stuck in Arkham).
Eventually, the Joker's accountant shows up with bad news: the Internal Revenue people want Joker for a massive amount of back taxes owed. Not wanting to go to war against the IRS ("I may be crazy enough to take on Batman, but the I.R.S.? No thank you!"), the Joker starts checking the stash of money he has left... only to find out that while the first ten million was legitimate, the rest of Barlowe's money is counterfeit. Barlowe's will and fake inheritance was all one huge last gag at the Joker's expense.
(on his deathbed
) Hiya, Joker. If you're playin' this tape, you've probably figured out you've been had. Yeah, I left you some cash, but only ten million — which, knowing you, you've already blown
. All the other stuff, money, jewels, and gold, it's all fake. See, I always hated your guts, and this was the perfect payback. By now, you're probably out of real money, the I.R.S. is after you, and you can't admit I fooled you
, or you'll be the laughingstock of the underworld. The joke's on you, sucker! I got the last laugh after all! (laughs, chokes, and uses his oxygen mask
Suddenly stuck back at poverty level, only now with the I.R.S. breathing down his neck, the Joker decides on doing what he does best: commit the biggest heist he can and save his hide.
- Batman Gambit / Thanatos Gambit: Willing millions of dollars to an enemy, knowing he'll spend it all, and then find out the rest is fake.
- Bill... Bill... Junk... Bill...: Joker plays out this trope looking for a replacement for Harley Quinn. He takes a long pause on a large, fat man before dismissing him. Then after he makes his choice, he promptly muses if he should have gone with the fat guy. Even funnier when you realize the guy was an animated caricature of Harley Quinn creator Paul Dini.
- Blunt Yes: The Joker and Harley Quinn ran out of gas during a escape. When he berated her for not refueling the car, she reminded him they were broke and asked what he wanted her to do: "fill the tank, shoot the guy and drive off?" The Joker silently nodded and she complained he didn't tell her before.
- Calling Card: Joker comments this is how Batman will know it's him if he tries to commit a crime to rebuild his fortune.
- Continuity Nod: Ernie, Joker's lawyer, mentions of the laughing fish.
- Cute, but Cacophonic: Fake Harley.
- Dangerously Genre Savvy: Realizing that using of his trademark gadgets will send him to jail, Joker plans on committing the crime by not using one of those gadgets.
- Dartboard of Hate: In Harley's Arkham cell, there's a picture of Batman full of darts.
- The Ditz: The replacement Harley is even ditzier than the original, referring to the Joker as "Mister G".
- Dramatic Shattering: When Barbara suggests that the Joker might really be reformed, Batman breaks a device he's working on.
- Driven by Envy:
Joker: I'm sure old Batboy is eating his heart out.
Penguin: Living well is the best revenge.
- Driven to Suicide:
Batgirl: Don't be stupid! You can't save that money!
Joker: I don't wanna save it! I wanna go with it!
- Falling Chandelier of Doom: A chandelier falls on a mook
- Film the Hand: Barlowe's bodyguard angrily blocks the camera with a hand at the end of his interview.
- A Fool and His New Money Are Soon Parted
- Forgot to Pay the Bill
- Frivolous Lawsuit: Parodied this with an unnamed Johnnie Cochran lookalike popping up to say a catchy line to support a lawsuit. In the commentary for one such episode, the creators note how dated the joke wound up being. Joker used high-powered lawyers to get acquitted of his various crimes (clearly referencing Cochran's most famous case): "If a man's filled with glee, that man must go free!"
- Intimidating Revenue Service: Even the Clown Prince of Crime is afraid of them. "I may be crazy enough to take on Batman, but the I.R.S.? No-o-o-o, thank you!"
- Keep the Reward: The Joker tries to give Batgirl and Nightwing money after they save his life; the heroes disdainfully crumple up the cash and drop it at his feet.
- The Mole: Ernie poses as The Joker, apparently to provide the real Joker with an alibi, and Batman leans on Penguin to help flush him out.
- Money to Throw Away: Hopefully most of the money Mistah J was tossing was the counterfeit stuff King Barlowe had tricked him with.
- Not What I Signed On For: Joker hires a replacement for Harley, claiming that it's cheaper than buying the real one out of jail. The one he gets isn't nearly as good as the real one, and she says twice that this "wasn't in the job description" (the second time when she's arrested; still, this was the Joker... she should have known better. Still, she can take comfort with the fact that the real Harley did get revenge on the Joker for the insult...)
- Now You Tell Me:
- An Offer You Can't Refuse: Barbara uses this to persuade Penguin in letting her and Dick in the Iceberg Lounge.
- Paranoia Gambit: When asked by Penguin what his scheme is, Joker remarks that he has none; the knowledge that the Bat-family can't touch him and that it's upsetting Batman is good enough.
- Passed Over Inheritance: The gangster who'd worked for Barlowe for years was upset that the Joker inherited the money instead of him. It's not known how he reacted if and when he learned the truth.
- Pretty in Mink: Some of the socialites at The Penguin's club are wearing fur wraps.
- Save the Villain: Batgirl and Nightwing do this when Joker is attacked by a rival gangster, much to their dismay.
- Schmuck Bait: When Harley escapes, the guards note that the laundry chute is the best possibility, but dismiss it, as it's laundry day. Cut to Harley stuck in the washing machine.
- Screw the Rules, I Have Money!: It's heavily implied The Joker bribed a psychiatrist into declaring him sane. The doctor denies this, while getting into his brand new car with a girl.
- Shoot The Television: The Joker shoots the Video Will in which his benefactor reveals most of the money is fake.
- So You Were Saying...?: When Batgirl comments that now that Joker's rich, maybe he'll give up crime. This really pisses Batman off.
(Batman breaks the disk in anger)
Batgirl: Right, I'll call Dick.
- Suspiciously Similar Substitute: "Fake Harley" is a deliberate example. The Joker hired her because it was cheaper than paying for the real Harley's release from Arkham, but he grows to regret it and a pissed-off Harley gets back at him for it in the end.
- Swirlie: Batman tortures the newly wealthy Joker's accountant Ernie into divulging the clown's whereabouts by sticking the guy's head in an Iceberg Lounge toilet and flushing. Repeatedly.
- Take a Third Option: Since Joker has two choices (either go to jail for tax evasion or admit that he's been fooled and become a laughing stock), he chooses to commit a crime to get his fortune back.
- Terrible Interviewees Montage: The Joker trying out new Harley Quinns after abandoning the original in prison (she gets her revenge at the end of the episode). A string of less-than-stellar ladies (and a cameo of Paul Dini in a Harley suit) meet his ad. He ends up hiring a busty but not-too-bright actress, who can't even spell Joker and calls him "Mistah G"; best summed up by the Joker's muttered line, "I should've gone with the fat guy."
- Trouble Entendre: Harley invokes this trope before exacting revenge against The Joker by beating him with her nightstick.
Quinn: Hiya, Mistah J... Welcome to the club.
- Unexpected Inheritance: The Joker certainly didn't expect to inherit his rival's wealth. The visit from the Intimidating Revenue Service and the rival's Video Will made him understand.
- Woman Scorned: Harley didn't take it well when the Joker dumped her for a new hench-girl.
