My personal opinion of the current Top Ten Joker/Harley "squee" moments. Subject to change! ;)

10. JOKER/MASK – I’LL NEVER CHANGE
Harley is worried The Mask will change her beloved Puddin’. He reassures her and gives her a big ole lovin’ kiss before the Bats interrupts.
Whilst this series is not a fan favourite for many good reasons, I really love this little moment of unusual gentle affection between J&HQ. Very, very cute!

9. GOTHAM ADVENTURES #14 – I’LL TAKE WHAT I CAN GET
A mind-controlled Joker enthusiastically welcomes Harley back to Arkham and compliments her on her wonderful schemes, declaring that he wants to hear ‘all about it’. Harley knows he’s only being nice because he’s been affected by the mind-controlling drug she’d been using, but states: “But you’re also a dangerous, murdering psychopath… so I’ll take what I can get.”
It’s just so cute to see a mind-controlled Joker holding Harley’s hand and smiling tenderly down at her, even though you know it’s not going to last! I also like to wonder if he’s at all aware of what’s going on and what the later reaction will be…

8. WILD CARDS – TWO OF A KIND
Harley’s jealousy of Ace has been roused by Batman’s goadings and she comes back to open up a can of whup-ass on her beloved Puddin’. But he placates her, saying they’re ‘two of a kind’ and she’ll always come back to him. She jumps into his arms for a squishy hug.
Yeah I know he goes ballistic on her almost immediately afterwards, but I just really love seeing Joker cuddle Harley so affectionately. It just doesn’t happen often enough – although if it did happen more often, it’d be totally out of character and I’d hate it. Oh well. Hehehe.

7. MAD LOVE – IT FELT LIKE A KISS
A broken and bruised Harley Quinn is wheeled back to her cell at Arkham, bitterly swearing Joker off for good. But there’s a rose in her cell with a little note: “Feel better soon – J”, and Harley’s love is back in bloom once more. When Dr. Leland asks her what it felt like to give everything she had to someone who used and abused her, Harley responds: “It felt like a kiss!”
Is it cheating, because this scene doesn’t directly feature Mistah J? That’s why it comes in at number seven instead of further down the scale. One of those perfect, beautiful moments illustrating the cyclical nature of Harley’s infatuation and the masochism inherent in it. Gorgeous!

 6. HARLEY AND IVY – YOU FOUND ME!
Joker’s tracked Harley down to the toxic dump her and Ivy are using as a hideout. Harley jumps joyously into his arms for a cuddle and pat on the head, ecstatic he’s gone to the trouble, despite his less than above-board means.
It’s the way he shuts his eyes and pats her head that does it for me. Ostensibly, his main motivation for tracking her down was to nick the swag she and Ivy had hauled, but we all saw how he was suffering without her – and the photo of her on his desk. A little reminder to her of his awesomeness and he knew she’d come back of her own accord! (that’s my story and I’m sticking to it!) But I also love Harley's hopeful but disbelieving 'Puddin'?' followed by her ecstatic 'ya found me!' and leaping into his arms. A great moment!

5. BATMAN ADVENTURES #28 – ZOSE EYES, ZOSE LIPS…
Harley, disguised as a German Psychiatrist in Arkham, becomes distracted by Joker’s ‘very, very handsome face’ whilst extolling his virtues to the dubious doctors. She throws herself on Joker for a passionate kiss, much to everyone’s shock. Finishing the smooch, she leaves her false moustache behind on Joker’s mouth and turns to everyone with an oblivious: ‘Vhat?’
This moment is just hysterically funny. It still gets me to laugh out loud. It’s too precious for words. Even though Joker is not really a voluntary participant in this moment, Harley getting carried away with her musings is too golden, and the sight of her moustache on Joker’s mouth is achingly hilarious.

4. HARLEY QUINN #5 – THE LOOK OF LOVE
Harley’s first session with Joker. He begins strangling her only to back off abruptly, suddenly startled by a look he sees in her eyes – the look of love. Commenting to himself that a woman like her only comes along ‘once in a lifetime’, he turns back to his doctor, leans over her with a charming smile and enquires: “So what did you want to talk about - -  Harley?”
DROOL. This is sexy in all the wrong (and subsequently, right) ways! Joker straddling Harley with his hands around her neck, the look on Harley’s face as she gazes at him, Joker’s quiet realisation followed by his cunning. It’s delicious and really sets the dynamic between the two up.

3. HARLEQUINADE – BABY, YOU’RE THE GREATEST!
Joker goads Harley into shooting at him and she does so, only for the gun to be revealed as a trick one. Harley cowers but Joker laughs and tells her she’s “the greatest!” welcoming Harley into his arms for a big ole hug and, I’m sure, a smooch if it wasn’t for the censors.
I just about died the first hundred times I watched this scene, and it still makes my heart flutter. It’s just something about the interaction, the glorious facial expressions, the little ‘ee!’ Harley makes and the way Joker sweeps her up into his arms and swings her around, not to mention the camera panning back so they can be surrounded by the little heart-shaped balloon. Classic Joker/Harley!

2. HARLEY QUINN – I HATE THOSE FEELINGS!
Joker traps Harley in an amusement park rocket, set to hurtle into space and end her life. As the rocket takes off, Joker makes a confession – he’s starting to care for Harley, the first time he can remember in many years having feelings such as those. Only problem is: he hates those feelings and sees the solution as getting rid of her!
This is just so perfectly Joker. The solution to uncomfortable, inconvenient feelings of affection? Destroy the object of them! Yes, it’s twisted, sick and wrong and that’s why we love it!

1. EMPEROR JOKER – MY DAME IN LIGHTS
Joker shares his very personal reasons for wanting to destroy the Universe, finishing with the revelation that in the new, blank Universe, people like him will “never come into existence”. Harley entreats him to spare her life, saying she thought everything she’d done for him might count for something. With an uncharacteristically soft look, Joker urges her to “c’mere” before tenderly kissing her. He then turns her into a constellation of stars and tells her she has “the best seat in the house for Armageddon”; finishing with “I always wanted to see my dame in lights… heh. Even in a moment of abject saccharine, I still got it.”
I almost cried when I first read this page. It is so exquisitely beautiful and understated, whilst remaining true to Joker and Harley’s characters. It is one of the rare moments of pure affection on Joker’s part, without a manipulative reason behind it. Obviously, Joker wasn’t going to “spare” Harley, just not his style. Instead he made a romantic gesture of Hellenic proportions, transforming the one person who’d always loved him no matter what he did or was, into something incredibly beautiful and enduring. My absolute favourite squee moment.
