Poison Ivy watches a gardening show in an Arkham Asylum lounge, until the Joker arrives and changes the channel. A guard resolves their argument by switching the channel to a third option, which turns out to be a news report about Cameron Kaiser's new casino resort. The casino's theme is revealed to be based on the Joker (though Kaiser claims it's the generic playing-card joker, not the "criminal fruitcake"). Outraged, the Joker rants about Kaiser cashing in on his image, and then feigns illness in order to make an escape.
Meanwhile, Bruce checks into the resort, discovering that the Joker-themed wallpaper was added at the last minute to an already-papered wall. As Batman, he takes a look at the records, discovering that the casino originally had a medieval theme. One of Kaiser's guards (the same guard earlier seen at Arkham, indicating that the Joker's escape was set up) interrupts him, but he slips away.
The Joker arrives at the casino, reveling in its tribute to him and almost regretful about his plan to blow it up. Mistaken for a casino employee, he gets assigned to deal a blackjack table, where he quickly annoys the guests into leaving. Kaiser is alerted to the oddity, but seems strangely unconcerned.
Bruce drops by the Joker's table, jerking his chain and confirming that he is the real Joker and not a costumed employee. He slips away and returns as Batman, but accidentally grabs the wrong "Joker," giving the real one sufficient warning to escape.
Kaiser watches on the security monitors as the Joker plants explosives in the basement (full of casino-themed attractions for an unfinished amusement park area), then orders his helicopter to get ready to leave. Batman confronts him, revealing that he's figured out Kaiser's plan to provoke the Joker into destroying the casino so he can collect on the insurance. Kaiser then stuns Batman with an electric-shock trap and has him dropped into an elevator and sent to the basement.
In the basement, the Joker knocks out the still-woozy Batman and straps him to a giant roulette wheel. Batman tells Joker how he's been played for a patsy in Kaiser's insurance scheme. Outraged at this, the Joker disconnects the bombs and leaves to confront Kaiser himself, while still leaving a grenade to take care of his foe.
Batman escapes and finds Kaiser's helicopter pilot knocked out. He takes the Bat-glider to intercept the helicopter where the Joker is holding Kaiser prisoner, intending to kill him and run the casino himself. After a struggle, the helicopter crashes into the casino, where Batman finally captures the Joker and sends him crashing into a slot machine, which showers him with coins.
Back at Arkham, the Joker tries to turn off a news report about the fiasco. However, Poison Ivy, the Mad Hatter, and the Scarecrow demand that he turn it back on, much to his annoyance.
Tropes in this episode include:
- Artistic License Law: The Law and the Multiverse webpage explains it in detail, but the nutshell of it is: Kaiser's scheme has "Insurance Fraud" written on the wall so clearly that had he tried it in Real Life, he would have been in serious trouble with the law long before the Joker broke out.
- In fact, according to the same blog linked above, the authors are pretty confident that Joker-related mayhem wouldn't even be insurable in Real Life under terrorism, war or civil unrest exclusions. So not only was Kaiser's plot tailor-made to unravel early on, but even if it HAD worked, good luck on him getting the insurance company to make him whole...
- Batman Gambit: Kaiser, hoping Joker would blow up the casino, which would allow him to collect the insurance money and get out of paying off his debts. The Joker admits he was pretty impressed.Joker: It was a scheme worthy of me, Kaiser. The way you got me riled up and turned me loose on this place!
- Beat Them at Their Own Game:
- Kaiser tricks the Joker.
- And then there's Bruce out-cheating the Joker at cards by distracting him with Stealth Insults.
- Blatant Lies: Kaiser's claim that the casino is supposed to be a tribute to the Joker card in gambling. This might have held more water had he not dressed up the staff in the Jokers iconic purple suit (the Joker cards usually wear jester outfits), not to mention the Harley Quinn costumes.
- Book-Ends: The episode begins and ends with the Joker in the rec room of Arkham Asylum arguing about what to watch on TV.
- Bread, Eggs, Milk, Squick: Joker loudly declares what he'll do in retaliation for the Joker's Wild casino.
- Breaking the Fourth Wall: As Joker escapes from his Cardboard Prison, he yells Don't Try This at Home, kids.Joker: I'll protest! Yeah, I'll sue! Then, I'll rip his lungs out!
- Bullying a Dragon: Kaiser finds out that provoking a murderous psychotic wasn't a good idea. Well, his plan would have gone through if Batman hadn't figured it out and told the Joker.
- Cool Car: The Jokermobile, which seems to be first prize in a raffle at the casino; the Joker commandeers it to escape from Batman, wrecking much of the casino and the car itself in the process.
- Corrupt Corporate Executive: Cameron Kaiser has run out of money to fund his casino... so he decides to commit Insurance Fraud by deliberately pissing off one of the greatest maniacs on the planet and hoping he will wreck the place so he can collect, obviously not caring about the possibility of what may happen to all of the innocent people that will inevitably become collateral damage.
- Disproportionate Retribution: An entrepreneur opens a casino in Gotham City based on the Joker's likeness and gimmicks. Joker is so incensed that a complete stranger would try to "cash in on my image" that he plots to blow the casino up. Ironically, the entire point of the entrepreneur cashing in on Joker's image was that he wanted Joker to come and trash the place. The entire place was set up for an insurance scam. Too bad for him, the Joker eventually decided he would rather kill the guy and run the place himself...
- Distaff Counterpart: All the male employees at Joker's Wild are dressed like the Clown Prince himself. All the female employees are dressed like Harley Quinn, who otherwise doesn't appear in this episode.
- Don't Try This at Home: The Joker escapes from Arhkam with a rather dangerous-looking stunt: tying a rock around a rope made from bedsheets, using it as a grapple to snag a truck passing by the asylum, and using it to pull himself over the fence. He laughs, "Don't try this at home, kiddies!" before he pulls it off.
- Foreshadowing:Summer Gleeson: Mr. Kaiser, why build a casino seemingly in honor of one of history's most notorious outlaws?
Cameron Kaiser: Summer, please. The joker is a classic symbol long associated with cards and games. I can't help it if there's a passing resemblance to some criminal [briefly glances at the camera] fruitcake!
Joker: [making his escape] What a maroon.
The guard:note I know you are, but what am I?
- The Ghost: The casino has female staff dressed as Harley Quinn, but the real Harley is surprisingly absent.
- A Glass in the Hand: The Joker is dealing at one of the casino tables as if he's a costumed employee. After being trolled by Bruce (to distract him while Bruce gets a good look and confirms that he's the real Joker), he crushes the chip Bruce tossed him as a tip.
- Insurance Fraud: Cameron Kaiser has gotten in over his head with the casino project, and came up with the idea of attracting the Joker's attention so that the place would get destroyed.
- Ironic Echo: Poison Ivy calls Joker a "psycho," he responds, "I know you are but what am I?" Which is what the security guard said when he let him escape.

- I've Come Too Far: Mr. Kaiser says this to Batman when he figures out Kaiser's plan.
- Lost in a Crowd: When the Joker shows up at the casino, he soon finds that all the card dealers and much of the staff are dressed in his clothes and wearing make-up and wigs to resemble him. This not only helps him escape Batman for a while (Bats accidentally accosts an employee whose makeup is particularly convincing), but also let him march right up to a blackjack table and start dealing.
- Mythology Gag: When Batman opens the second folder involving Joker during his investigation of Kiaser's office, Joker's alias is Jack Napier, which was Joker's identity in Tim Burton's original film.
- Nice Job Fixing It, Villain!: Kaiser sending Batman down to the basement so the Joker can deal with him is a huge mistake on his part; all it does is let Batman inform the Joker of Kaiser's actual intent, causing the villain to change his plans and confront Kaiser directly.The Joker: [to Batman] I hate it when you make sense!
- Off-Model: The Mad Hatter doesn't quite look like himself near the end.
- Offscreen Villain Dark Matter: The casino being nearly bankrupt was the reason Kaiser set up the fraud in the first place. Yet, he was able to re-stylize the entire thing, papering over the "Camelot" wallpaper and coming up with all new costumes, attractions, and a giant laughing Joker head for the marquee, and do so in secret.
- Paper-Thin Disguise: Kaiser and Batman (both of whom are expecting the real Joker to show up) can distinguish the genuine article from the costumed employees, but nobody else seems to have the slightest suspicion in that regard.
- Playing Sick: The Joker does this to set up his escape from Arkham. He has a particularly easy time of it, since one of the guards is working for Kaiser, who wants him free to destroy the casino.
- Pretty in Mink: Bruce's date wears a black fur wrap. She also looks just like the scorned socialite in Batman: Mask of the Phantasm.

- Kaiser is a variant of the name Caesar; in the 60s series the Joker was played by Cesar Romero.

- Spanner in the Works: Batman acts as one for Kaiser's plan when Kaiser subdues him and sends him down to the Joker, expecting the Joker to kill him. Unfortunately, he doesn't anticipate the Joker taking the time to rig up a deathtrap for Batman, giving the Dark Knight the opportunity to recover enough to spill the beans to the Joker.
- The Starscream: After the Joker learns about Kaiser's plans, he changes his mind about blowing up the Joker's Wild casino. Instead of destroying the place, he plans to kill Kaiser and take over control of Joker's Wild for himself.
- Stealth Insult: Bruce drops tons of these to confirm that the real Joker rather than a costumed casino employee is dealing him cards at the blackjack table—and also to distract him so Bruce can out-cheat him at cards.Bruce: Too bad it has to be in such gruesome surroundings.
[the Joker fumbles with the pack of cards, then recovers]
Joker: Don't care for the décor?
Bruce: Not hardly. All those horrible faces grinning at me. That would do things to my mind after a while.
Joker: [grumbling] Who says you have one?
Bruce: [looking at his cards] Yep, I'd be ready for the laughing academy if I had to stare at that ugly clown all day.
Joker: [infuriated] Why, I oughtta...
Bruce: [seemingly oblivious] Hit me.
Joker: [flipping over his cards] Twenty!
Bruce: [flipping over his cards] Oh, lucky me! Twenty-one! How nice! A little something for the Wayne Charity Fund! [tosses the Joker a poker chip as a tip] Good night...
