Harley Quinn is pronounced sufficiently cured to be released from Arkham Asylum. Batman solemnly congratulates her, and she assures him that she intends to put crime behind her.
Out on the streets, she alarms people by walking her hyenas, but stays out of trouble. Deciding that she needs to update her wardrobe, she stops in a clothing store and picks out a dress. Unfortunately, she hurries off with it right after purchasing it, not waiting for the clerk to remove the anti-shoplifting tag. A guard tries to get her attention, but this scares her and she starts running. When the store alarm goes off, she decides that people are still chasing her as a criminal, so she flees in a stolen car.
Batman and Robin try to catch up to her while there's still hope of straightening out the mess. Harley leads them on a chase as she heads for Boxey Bennett's place to seek help getting out of town. Bennett turns against Harley when she rejects their plan to hold Veronica for ransom, and a fight breaks out between the gang, Harley, and the heroes. Meanwhile, Harvey Bullock gets drawn into the chase, and Veronica's father General Vreeland shows up in a tank.
The chaos ends with Harley captured and returned to Arkham. However, Veronica Vreeland declines to press charges, since the kidnapping was accidental and Harley meant no harm, so she has a good chance of getting out again. Batman shows up with Harley's dress (she did pay for it, after all) and wishes her luck in turning her life around. She gives him a peck on the lips, then a big long kiss as Robin and Poison Ivy look on bemusedly.
- Absentee Actor: This is notably the only BTAS episode (before the retool as The New Batman Adventures) where Harley appears without the Joker.
- The Alleged Car: It's a miracle that Bullock's car can even drive by the end of the episode.
- Animation Bump: Of all the episodes Dong Yang animated. Rumor has it that TMS did some uncredited work on the episode.
- Any Last Words?: When Boxey is holding Harley at gunpoint:Boxey: Any last words?Harley: Just one... BABIES! (Harley's hyenas crash through the wall and attack Boxey)
- Bait-and-Switch: Harley recognises that chin... Oh! It's Bruce Wayne!
- Barrier-Busting Blow: Harley's hyenas burst through a wall to attack Boxey after Harley calls for them.
- Brake Angrily: What Harley does after noticing the truck Boxy's driving coming right towards her. Unfortunately, the car stops right in front of General Vreeland's tank.
- The Bus Came Back: Boxy Bennett, the crooked owner of a Gotham City nightclub, made a previous appearance in "Harlequinade". There's even a Continuity Nod to "Harlequinade", with Boxy grumpily reminding Harley that his place got trashed the last time she visited him.
- Butt-Monkey: Harvey Bullock, along with his car.
- When Veronica Vreeland first appeared in "Birds of a Feather", she and her friend Pierce were reminiscing about the time the Joker previously crashed the party of a friend of theirs for a hold-up. Upon meeting Veronica here, Harley brings up that same party and adds that she pointed a gun at Veronica's head.
- Boxey points out that the last time Harley Quinn showed up at his door she not only destroyed his club, but brought Batman down on him as well. This occurred in "Harlequinade," where Harley was helping Batman find the Joker.
- Can't Stay Normal: To her credit Harley tries, but she has a Freak Out! when a security guard comes to remove the anti-shoplifting tag. She sadly says, "Home again, home again, jiggedy-jig" as Batman returns her to Arkham.
- Dating Catwoman: Played for laughs; at the episode's end, Harley gives Batman a quick peck on the cheek for his kindness during the day's mishaps. Then she stops, thinks it over, and gives him a passionate kiss on the lips, shyly asking him to call her after she breaks the kiss.
- Death Glare: Administered by Gordon to a furious General Vreeland after the general knocks over the commissioner's coffee mid-rant. The general backs down.
- Dog Walks You: Well, Hyenas Walk You When You're Wearing Rollerskates, anyway.
- Doomed New Clothes: Veronica Vreeland. There she is, buying a new dress for her date with Bruce Wayne and along comes a spooked Harley Quinn.
- Evil Cannot Comprehend Good: While Harley isn't really acting evil in this story, she's at a loss to understand why Batman would go out of his way to help someone who'd never given him anything but trouble.
- Additionally, the whole mess starts in the first place because in Harley's experience, the only reason a security guard would be chasing after her demanding merchandise back is because they think she stole it. It never once occurs to her that they just want it back long enough to remove the anti-theft tag and send her on her way, and she's in such a panicked state that she doesn't listen to them trying to tell her what the problem is.
- Evil-Detecting Dog: Inversion. Harley's pet hyenas act viciously when they encounter Bruce Wayne, but she doesn't realize that there's probably a reason for it.
- For Want of a Nail: Kidnapping, property damage, a freaking tank rolling through Gotham, blasting craters into the street... Who knew one little dress going on sale could end up causing so much trouble?
- Friendly Enemy: During the Arkham scenes, everyone's on unusually good speaking terms with each other. They've gotten so used to battling each other...
- HeelFace Door-Slam: Poor, poor, Harley. And because Status Quo Is God, she never truly reached this point again. (Or does she?)
- Hey, Wait!: Harley Quinn meets Bruce Wayne and covers the top half of his face, saying she recognizes that chin. Bruce thinks he's been found out, but it turns out it was actually Bruce Wayne she was recognizing by his chin.
- Idiot Ball: General Vreeland really doesn't seem to consider the issues that might be associated with ordering a tank to open fire on a car that his daughter is in, in the middle of civilian population. Furthermore, a tank from one's own country rolling into a big city without a parade is usually either a harbinger of war or of a coup d'etat...
- Insane No More: Harley is officially declared sane and released from Arkham. Her psychiatrist also states at the end she is making real progress.
- Karma Houdini: General Vreeland for driving a tank through the Gotham streets to save his daughter. He probably caused more damage in a few minutes than Harley did during the whole day.
- Lemming Cops: At the end there's a large pileup of cars from characters seen in this episode.
- Limited Wardrobe: Bruce actually goes suit shopping with Veronica Vreeland, who points out that Bruce needs a better sense of style.
- Harley realizes the same thing, comically mistaking the bystanders' horrified reactions to her hyenas as their disgust in her outdated roller skate girl outfit.
- Mood Whiplash: In the opening scene, Batman and Robin bring the Scarecrow back to Arkham:Scarecrow: (ranting) I am the master of fear! The lord of despair! Cower before me and witness terror!
Harley: (cheerful) Hi, Professor Crane!
Scarecrow: (calm) Good evening, child. (back to ranting) Worship me, fools! Worship me! Scream hosannas of anguish to Scarecrow, the all-terrible god of fear!
Robin: (deadpan) I think he's getting better.
- Mythology Gag: During her final confrontation with Batman, Harley uses a line once famously professed by her puddin':Harley: I'm having a bad day!
- The Nose Knows: Harley's hyenas snarl and bark when they see Bruce Wayne, because they probably realize he smells the same as Batman. Harley doesn't pick up on it.
- Not So Different: Harley Quinn freaks out and takes a hostage over a dress. General Vreeland freaks out and drives a tank through a big city, a move that's insanely dangerous and sends horrible signals (the most serious of them being a coup d'etat) over his daughter. Bullock causes his share of property damage, to include a truck exploding, over his coffee...
- Oh, Crap!: When General Vreeland shows up in a tank.Veronica Vreeland: Daddy!Harley Quinn: Daddy?!
- Papa Wolf: General Vreeland gets so upset over his daughter's kidnapping that he starts calling in military forces to try and rescue Veronica, culminating in his commandeering a tank and driving it down the streets of Gotham after Harley, taking potshots at her all the while.
- Pet the Dog:
- After all the criminals and heroes crash, Harley tosses Veronica into her father's arms and flees. She lampshades it as her "good deed for the day".
- Batman gives the dress to Harley after returning her to Arkham, since she did pay for it.
- Poor Communication Kills: A variant; Harley pays for her new dress, and then immediately leaves as the cashier is putting the money in the register, not giving her time to remove the security tag, nor listening when the cashier tries to call Harley back. When she, naturally, sets off the security alarm, Harley panics too hard to listen when the security guard tries to explain she's set it off with a security tag; instead, she presumes he's trying to take her dress back, and she believes she's being unfairly punished for her criminal past. This leads to her running off to the women's room, donning her harlequin outfit, and making a break for it, grabbing Veronica Vreeland for a hostage in the bargain. If she'd just stopped and listened to what people were saying, she could have avoided the whole mess that ensued.
- Redemption Failure: Harley Quinn is pronounced sane and released from Arkham, and plans to live as a law-abiding citizen. Unfortunately, a misunderstanding while purchasing clothes make her think she's being arrested even when she's doing nothing wrong, and she goes on an actual crime spree to avoid getting caught.
- Shout-Out: Harley Quinn, upon returning to Arkham, says the line, "Home again, home again, jiggity jig." It's a reference to the scene where one of the toys says the same line when J.F. Sebastian comes home with a woman in Blade Runner.
- The line itself is originally from the Nursery Rhyme "To Market", which goes "To market, to market, to buy a fat pig / Home again, home again, jiggity jig / To market, to market, to buy a fat hog / Home again, home again, jiggity jog."
- Society Is to Blame: Harley uses exactly this phrase when she thinks she's being framed.I tried to play by the rules, but noo, they wouldn't let me go straight! Society is to blame!
- Tank Goodness: Harley Quinn ended up being chased by one driven by General Vreeland after accidentally kidnapping his daughter Veronica.(while driving away)
Veronica: Wait-what are you doing? That's my father.
Harley Quinn: No, that's your father, IN A TANK!
- Tempting Fate: A semi-rehabilitated Harley Quinn ends up being chased by the police, as well as Batman and Robin, after a simple misunderstanding. After taking Spoiled Sweet Veronica Vreeland hostage, she then ends up being chased by gangsters who wish to ransom off the debutante. After Veronica realizes Harley really means her no harm, she agrees to drop all charges, if she gets out of this in one piece. A delighted Harley states: "For the first time today, things are finally looking up!" Enter Veronica's hysterical Army general father, bearing down on them in a tank, Patton-style.
- Then Let Me Be Evil: Harley thinks that she's being chased as a criminal even though she didn't do anything wrong, so she steals a car and tries to go on the lam.
- Visual Pun: When having her freak out and going back into costume, Harley declares that she's armed before smacking Bruce Wayne with a dummy's arm.
