How about the first two times, of many, that Ranma hands Kuno his ass. They are pretty much the only time Ranma and Kuno have a fight that is even halfway serious. And it shows just how ridiculously powerful Ranma is.
When fighting the biggest head of the legendary man-eating dragon, Yamata No Orochi, Ranma was completely outclassed in terms of raw force, so she opted to prance around in an embarrassing female getup to get the perverted beast drunk or keep it distracted from eating Akane, while Ryoga and Shinnosuke were busy defeating the seven smaller much less formidable heads, and Akane sampled the healing moss from its back. It was finally put to sleep by a magic whistle. What made this both hilariously absurd and awesome is that Ranma stood up to a monster that she couldn't even damage, and was willing to behave in a humiliating manner to keep Akane safe.
And then Akane's own Moment of Awesome when she actually dove into the dragon's jaws in order to save Ranma from being eaten.
And let's not forget Ranma saving an unconscious Akane from the same fate earlier. By swimming all the way to the bottom of a lake that was deeper than the Orochi was tall, grabbing a boulder that was the size of a large car, and smashing it into the Orochi's mouth before it could finish closing its jaws. In his notably weaker female form.
Ryoga's most awesome moment — at least in the manga — might be when he fights Herb's minion, Lime, the likely physically strongest character in the series, and his foe gets the opportunity to put him in a stranglehold after Mousse accidenatlly distracts Ryoga. He has visions of the afterlife for a couple of seconds; then he has a vision of Akane living happily ever after with Ranma and never giving a thought to him again. This makes him feel very depressed.
Ryoga: SHISHI HOUKOUDAN!
And voilà - opponent flattened.
A key reason why you don't want to make Ryoga depressed; the Shishi Hokodan is more effective the more depressed you are (and he's got an unlimited supply of depression).
Even more impressive: Prince Herb, an extremely strong chi-user himself, was woken up and awed by the enormous chi Ryoga generated for the gigantic Sphere of Destruction.
Equally awesome was the fact that Ryoga later allowed himself to be buried alive in solid rock with Lime in order to retrieve the kettle that would get Ranma out of Mode Lock. Not only did he risk dying in order to help Ranma, he came charging up from the ground in a truly excellent Big Damn Heroes moment.
His and Mousse's behavior during that last battle against Herb and his lackeys crosses over into Heartwarming Moments territory as well, considering that they were doing it because Ranma was serving as a distraction against the much stronger Herb so that they could get the kettle to cancel their own Mode Lock... which was caused by them betraying Ranma to try and cure themselves earlier.
Ryoga gets another awesome Big Damn Heroes moment in the moxibustion storyline, in which Ranma is rendered (literally) too weak to hurt a child. Four of Ranma's enemies take advantage of this by ganging up on him. Just as Ranma is about to be completely overwhelmed, in steps Ryoga, who easily dispatches all four with a seriously badass Go Through Me look on his face.
And when Ranma finally gets Ryouga to come at him seriously (to put this in perspective, the bandanna'd boy shattered the massive boulder they were practicing on top of while honestly trying to apologize for being too gentle-hearted to fight the weakened Ranma seriously), he opens the fight by punching Ranma so hard that the pigtailed boy created a five meter wide crater on the side of the mountain that he'd hit. Ranma got his own Moment of Awesome at the end of the fight, however, when he figured out the final step of the Hiryuu Shouten Ha on the fly (because Cologne had forgot to tell him how to do it for real during raining) and hit Ryouga with a blast of cold ki and a tornado strong enough to oneshot his nigh-invulnerable opponent.
The climax of the whole "Ranma's Mother" ongoing plotline, as Ranma leaps off a cliff overlooking the ocean to save a falling Nodoka, heedless of all the cold water below (which would reveal his secret.) Just as he catches her mid-fall, he takes her sheathed katana and hurls it at the cliff-face with such force that it's embedded into the rock, providing a tiny (but adequate) foothold for him and Nodoka, instants before they either splatter all over the rocks or splash into the water. This is followed by the series' Heartwarming Moments.
Ranma defeating some of his most dangerous opponents using their own strength, and on-the-fly tactics, against them:
After the monstrous Pantyhose Taro had been extensively battered by both Ryoga, Ranma, Mousse, and Shampoo, Ranma let Taro swing him around on a length of pantyhose, only to use the elastic snap-back to kick the over four metres tall creature back several dozen meters into a hot spring. However, he also had to beat up Taro's even more battered human form right afterwards to finally knock him out.
During Ranma's struggle with the dragon-hybrid Herb, the villain had consistently wiped the floor with Ranma, who managed to stay alive by consistently taunting his foe to be careless, and the narrow plateau — and the mountain it was part of — they were standing on had started to crumble apart from all the blasts. Ranma then used Herb's overconfidence in his ability counter the Hiryu Shoten Ha gainst him, and when caught in the tornado collected Herb's discharged energies from the preceding battle into a gigantic ball of force which instantly KOs the Musk Prince, and then saves Herb's life from the ensuing landslide.
Learning a technique to mostly stay out of sight from Ryuu Kumon's lethal strikes, while loosening the soil around his foe, and then using the vacuum resulting from Ryuu's ultimate technique to summon up a huge surge of dirt that buries the opponent.
Using the phoenix-hybrid Saffron's mountain-top vaporizing flame-generation, in combination with a magic weapon with freezing powers as strong as Saffron's heat (and the ability to block or cut through nearly anything solid), to deliver the most concentrated Hiryuu Shouten Ha in the series, which freezes and shatters his foe.
Then proceeding to throw said weapon with perfect accuracy into a fitted slot on the head of a massive statue that Ryouga and Ranma (who was backed up by the cave-in-clearing force of a Shishi Hokodan) could barely dent, then using the leftover heat from the battle (which was sufficiently hot to significantly slow down his descent) to create a Hiryuu Shouten Ha on the fly that he then used to very precisely punch through the neck of the statue like it wasn't even there and then drop the head on the stump so that the water that would cure Akane would be shot into the air. And let's not forget that the first Hiryuu Shouten Ha that Ranma threw in this fight was sufficiently strong that it rerouted an underground river to Mt. Phoenix, thus possibly preventing Saffron from ever having to use Jusendo again.
Speaking of Saffron... Under normal circumstances, Ranma tends to avoid using anywhere near lethal or maiming force even when his opponents are trying to use instant kill techniques on him. After Akane's life got put on a timer and Saffron stood (well, flew) between Ranma and the cure, Ranma opened up the fight by slicing off Saffron's wings in the middle and dropping him off the side of a mountain, followed up with stabbing him in the arm and trying to freeze the guy to death, and ends the fight with the aforementioned freezing and shattering. Lesson learned: don't @#$% with Akane's life.
The 1ft-tall Cologne handing Ranma his/her ass effortlessly is par for the course, but the Watermelon Race Battle truly established her as the unsurmountable badass she really is, and completely outmatched him wihtout breaking a sweat: hitting water into the shape of a giant shark, creating waterspouts at will, and commandeering her own Great White shark.
Does the anime version, which takes place on a mountain instead of at the beach, count too? When Cologne first gets serious, she conjures a tornado. With nothing more then a flick of her staff. And then we have the equivalent of the Shark Fist battle, with her flying around on the back of a life-sized ice sculpture of a grizzly bear. And telekinetically flinging a few dozen ice boulders at Ranma to boot.
Ranma gets one in the first movie, when facing an opponent too fast to beat with his chestnut-fist enhanced speed, but who is dependent on chopsticks, he punches the ground so hard that the force goes through most of the floors of the tower that they were near the top of and the foundation beneath it to create a geyser that floods the room, then projects the water into blasts that are not possible for Kirin to block.
Speaking of the movies, Ryoga and Mousse each get one in saving the girls the anime typically pairs them off with. Mousse gets hit in the pressure points by feathers (twice!) but to his opponent's disbelief, he withstands them by sheer force of will. Then he delivers the knockout punch on his foe and save Shampoo in the process. Ryoga stumbles across Ukyo being held captive by a magic-wielding monkey-man, though initially the Lost Boy just says "Screw this, I've gotta find Akane!" After Ukyou convinces him to help, her captor decides to use a magic technique which cripples the victim with depression. Much like Lime's defeat, depressing Ryoga is a very bad idea.
Soun Tendo gets one that overlaps with CMOH. When Kasumi is possessed by the oni that makes you do evil things, he valiantly tries to endure because he couldn't bear to hurt his own daughter (a blow to the head usually gets it to leave), and shows he's a true father when he badassedly tells the thing to take his body instead, and get the hell out of his daughter.
Ranma Saotome keeps it short but epic with a quip in the manga version of the Romeo and Juliet farce:
Ranma: Did you really think sealing me in concrete and burying me in the yard was even going to slow me down?!
In the same vein as the above, Happosai's debut. Before the series, Genma and Soun finally escaped him by getting him drunk on barrels of sake. They then sealed him up in the barrel, chained it up, hurled it into a cave, tossed a sizable bundle of lit dynamite inside with him, then closed up the cave with a massive boulder wrapped in a shimenawa before it exploded. About a decade later, a lightning storm topples a tree and knocks the boulder away, whereupon Happosai heads to Tokyo, none the worse for wear. When Happosai arrives at the Tendo household, Genma and Soun list in terror what they did to him while blubbering it's impossible for him to be there.
Happosai: "You forgot to finish me."note Manga version dialogue / "It's your own fault for not finishing me off."note Anime version dialogue
ANY serious fight between Ranma and Ryoga is chock full of these.
Early on, we learned of Ranma and Ryouga's massive stamina when a "practice" session, in reality Ryouga trying to cripple Ranma and Ranma fighting for his life, lasted all night. Ryouga and Ranma literally fought for hours before Ranma could score a decisive victory.
And shortly after we have Kodachi exhausting Ranma in a Martial Arts Rhythmic Gymnastics fight. Kodachi herself, while defeated, was relatively fresh.
Kodachi's debut arc is full of awesome moments for her:
When we first see her, she's about to be attacked by four bandaged opponents. Ranma is about to intervene to protect her... Then has to intervene to protect them, as Kodachi knocked them down in one hit (not one hit each, one hit for them all) and has decided to whip them.
The Reveal about the attackers' identity makes this even more awesome: they are the top members of Furinkan's Martial Arts Rhythmic Gymnastics team, that Kodachi has already beat the crap out of once (hence the bandages: they were covering their bruises). That's why she had decided to whip them: because if they didn't get they were Overshadowed by Awesome the first time, she wouldn't go easy on them.
Furinkan's Martial Arts Rhythmic Gymnastics team got Akane to sub for them and fight Kodachi... Meaning that, under Kodachi's warped code of honor, she's now a legitimate target, and Akane has to fight for her life before her attacker decides she's decent enough to be annihilated on the ring and leaves.
Akane got injured from training too much, and Ranma subbed in. By the end of the battle, Ranma is about to collapse from sheer fatigue at keeping up with Kodachi without using directly hands and feet-and Ranma is the one who won.
Some of Kodachi's techniques during the tournament fight, showing up both her skills and just how much of a Combat Pragmatist she is (and what kind of insane sport Martial Arts Rhythmic Gymnastics, as all these techniques are legal if not stated otherwise):
The Thousand Clubs: she grabs two clubs and attacks with such speed it looks she's using twenty clubs... Then it's revealed she was using twenty clubs. Somehow.
Later she attacks with a club with pop-up spikes. This one is actually illegal... But she's so good she still manages to get away with it.
Suddenly she starts attacking with her ribbon as if it was a steel bar... Then she scores a hit, and it turns out it was a steel bar that she was masquerading as a ribbon. And she hits hard enough to hurt Ranma.
Ranma uses the ribbon to grab a table and use it as flail. Kodachi easily tops it by using her brother.
After the ring is destroyed and only the ring posts remain, Ranma uses the ribbon to attach herself to the ceiling and hit with a flying kick... And Kodachi just stays there with a smug grin: either she had instantly calculated that the length of the ribbon would prevent Ranma from actually hitting her, or she just expected to be kicked and win by disqualification, as bare-handed attacks are forbidden.
After Ranma comes back to her ring post, Kodachi reveals that she has effectively won, as she has manipulated Ranma in exhausting all her weapons and now cannot legally attack anymore, while Kodachi still has her ribbon and her second has a few items. Also, she's fresher than Ranma. Ranma wins anyway by destroying the post Kodachi was on and using its pieces to not touch the ground before Kodachi falls down, but it was one of her hardest victories-and she's visibly panting.
On a similar vein, Ryoga's introduction to the series. Not only is he introduced in his own badass way, stopping a boar the size of a tractor from charging him with one hand before throwing it through the air like a pillow, but when he gets to fight Ranma, he establishes himself as Ranma's real rival. Prior to this point, Ranma had only fought a few short bouts with the mostly outclassed Kuno, and occasionally been smacked around by the angry Akane. Ryoga was the first battle where Ranma got serious, showing off some amazing skills for both versions.
In the manga version, Ryoga appears at Furinkan for the first time by leaping to intersect Ranma as he's bounding away from an angry Akane. Ranma deftly avoids Ryoga's blow, a downward strike with his umbrella that craters the concrete he lands on. When they have their duel over a week later, Ranma initially avoids Ryoga seemingly effortlessly, until Ryoga manages to trap him by tying their wrists together with a bandanna. As they continue battling, Ryoga cuts Ranma's cheek with just the air pressure from his open-palm jab, which prompts Ranma to up his ante; at Ryoga's next strike, he seems to vanish into thin air, in reality ducking down and sliding through Ryoga's legs before backflipping onto Ryoga's shoulders, knocking Ryoga onto his face faster than the Lost Boy can blink. Then Ryoga gets out of that position by doing a one-handed handstand and throwing the two of them into the air. Whereupon Ranma kicks him so hard that Ryoga goes flying and scrambles to grab his umbrella, cutting Ranma's shirt open and causing Ranma to smash a nearby water fountain when he gets sloppy in his anger.
In the anime version, the "test" fight is lengthened to explain why there was a delay before the true duel; losing sight of Ranma, Ryoga goes charging off blindly and literally runs clean through Furinkan's ground floor and out onto the street on the other side. And this was long before the Bakusai Tenketsu training arc, so Ryoga was literally charging through walls on pure brute strength. The duel-proper is likewise lengthened; after grabbing his umbrella, Ryoga and Ranma leap clean over the sports fences and make their way to the street, where Nabiki intervenes; desperate to prevent herself from losing a bundle due to everybody betting on Ranma, she gives Ryoga some vitamins and a lie about them being steroids to pep him up. Ryoga promptly uproots a telephone pole to use as a club, chasing Ranma all the way to the local zoo. Initially, Ryoga has the upper hand, until he cuts open Ranma's shirt with the jagged end of his telephone pole and mocks Ranma as "sounding like a girl". The outraged Ranma promptly shatters Ryoga's telephone pole with a diving kick, scaring Ryoga so much that he loses his newfound confidence, before Ranma ends up smashing a water fountain and turning into a girl.
This then culminates in the mutually-canon scene when Ryoga throws his umbrella and several bandanna razor-rangs at Ranma & Akane. Ranma promptly knocks Ryoga's umbrella out of the air with a kick, grabs it in one hand and uses it as a shield, whilst at the same time grabbing Akane with the other hand and leaping meters straight up to get Akane out of harm's way into the safety of a nearby tree. If this isn't bad enough, keep in mind that Ryoga's umbrella is so heavy that Akane found it difficult to budge, and Akane herself isn't a bundle of feathers. This gets more impressive retroactively, when it's confirmed in a later story that Ranma's female form has less strength than his male form, meaning he pulled off a stunt like that with a distinct strength handicap.
Shampoo's first fight with Akane. Until then, Shampoo's strength and skills and Ranma's fear of her (as she was trying to murder her girl form at the time) had been played for laughs... Then we get to see why Ranma feared her, a piece at a time:
The fight is originally unseen, only the aftermath of Akane knocked out... Without having been physically hurt. She simply lost memory of Ranma, somehow.
Later we hear from Ryoga what he saw as P-Chan. He was knocked out early when Shampoo accidentally landed on him, but managed to see that Akane threw the first punch with all her speed... And Shampoo casually jumped over her, turned mid-jump, and landed right behind her (this is when Shampoo's feet connected with Ryoga).
Finally Genma recounts what Shampoo did to Akane: she washed her hair with a special shampoo that, combined with a pressure point attack, erased Akane's memory of Ranma and knocked her out from the strain, and then dried it... In 56 seconds. In the anime, she did it in 5 to 6 seconds.
It's worth noting that this was Shampoo showing mercy: she could have easily killed Akane in a dozen ways, but (in her own twisted way) she liked her so she deliberatedly went the complicated way to make sure Akane wouldn't pick another fight without injurying her.
A few of the other confrontations between them show how formidable Shampoo is:
Right at the end of Shampoo's introduction arc, Akane has recovered her memory, Shampoo notices... And faster than Akane can see, her fingers are a few centimeters away from executing a deadly pressure point attack, only blocked by Ranma's intervention.
At the start of the Super Soba arc we get Akane easily defeating arm wrestling machines patterned after Sumo wrestlers, then she gets to the Yokozuna (highest rank in Sumo) one and has trouble... Then the machine speaks declaring Akane is too early to hope to win, topples Akane, and bursts open to reveal Shampoo was hiding in the machine and had put her arm in place of its mechanism.
Later in the Super Soba arc Akane, who is now super strong, wants to challenge Shampoo, and finds she had been spending her free day winning a martial arts badminton tournament. Thanks to her now greater strength Akane overwhelms her... Then Shampoo stumbles on Happosai with the last super soba dish, eats it, and dares Akane to face her with rackets taller than they are and the ball replaced by a gigantic bell, so heavy Ranma couldn't lift.
In the Waterproof Soap arc Shampoo needs to manipulate Ryoga to recover said soap... And so she pulls out a pressure point technique to have Akane hug Ryoga.
When facing off against Pink and Link, the twins finally get the advantage over their old enemy by poisoning her with a snake plant, whose venom leaves its victims in an eternal slumber. They beat her a hundred times, then get ready to stab her in the heart with a pair of daggers... only for Shampoo to instantly snap awake, disarm them both, and them viciously pummel them. The twins are left aghast at how Shampoo could have shaken off the eternal sleeping poison... and are then terrified to realize that she hasn't woken up; she's just so well trained in martial arts she is capable of fighting in her sleep. And even trying to kill in that state, as she attempts to strangle one of the twins with her bare hands whilst still being out cold.
In the manga version of the "Nabiki the Fiancee" arc, Nabiki decides to deal with the other fiancees by playing them against each other. She successfully get Ukyo and Kodachi to try and buy Ranma and trying to one-up each other with their offers, they're getting angry and about to fight... Then Shampoo shows up and outsmarts Nabiki by casually stating that if Nabiki dies then they get Ranma for free, thus getting Ukyo and Kodachi to stop fighting and instead join forces with Shampoo to do just that.
According to the inserts in more recent reprints of the manga, Shampoo is flat-out the strongest of the fiancees, in the same league as Ranma and Ryoga. And without the muscle mass she'd have as a boy.
Even better, she's also far stronger than Mousse. There's a good reason if Shampoo doesn't consider him as marriage material and Cologne was so fast to state he wouldn't marry her: Shampoo is that much stronger than Mousse, and Shampoo wants someone even stronger than she is for a husband.
How Mikado Sanzenin and Azusa Shiratori establish their credentials as fighters: by defeating one hundred hockey players. In nine seconds (it was actually timed, as it was a training). And not only they looked as stylish as expected by a figure skating pair, Azusa was kicking with her ice skates and still managed to not actually harm anyone.
That is followed by one for Ranma: enraged for being kissed, Ranma, who could barely stand on skates, challenged Mikado on his turf... And left him fainted standing up, courtesy of five hundred and eighteen punches. He got quite beat up in the process, but that was on ice, and it's implied Ranma would have just massacred him on normal terrain.
To start said duel, Ranma punches the ice rink in his rage, splitting the ice to create a crack that stretches from where he is on the edge to where Mikado is, towards the center. Then Ranma leaps into the air and makes a diving punch that Mikado sidesteps, leaving Ranma to hit the icerink headfirst so hard he creates a crater. Mikado smugly declares that Ranma must be unconscious after a move like that, chastising him for launching a "suicide strike" so early in the match, only to get the shock of his life as Ranma suddenly leaps out of the crater and attacks Mikado from behind, which Mikado narrowly dodges, but reacts to with naked shock. Then Ranma charges Mikado again, only to trip and skid across the length of the ice rink on his face before hitting the far wall with such speed that he smashes clean through it... and then he gets right back up again. Finally, Mikado decides to use his ultimate personal technique, the Dance of Death, which pulls Ranma into a whirling vortex in which Mikado can pummel him constantly. It ends with Ranma being ejected out of the vortex straight up and arcing through the air before crashing back onto the rink headfirst. Akane asks if Ranma can still stand, and Ranma proceeds to leap straight up and somersault into what would have been a pinpoint landing... if he hadn't lost his footing on the ice and fallen over, knocking himself out cold at last. As Akane takes Ranma away for medical attention, Azusa brags that Mikado won, but Akane calmly corrects her, which is when Azusa looks at Mikado and realizes that he's been beaten so thoroughly unconscious that he's still standing straight up with his eyes open.
During the duel against Mikado and Azusa in the "Charlotte Cup", Ranma and Akane are sent flying when Azusa loses her grip during the Goodbye Whirl technique, launching them at massive velocity right at the arena wall. Without hesitating, Ranma twists them around in midair so that he hits the wall first, cushioning the blow for Akane. The effort leaves a huge crater in the wall and Ranma lying unconscious on the ice...still holding Akane's hand. Mikado declares that an impact like that must have broken every bone in Ranma's body, asserting that nothing human could have survived such a blow, which causes Akane to break down in tears and insults... whereupon Ranma regains consciousness, quietly calls her out for calling him names, and assures her that he's okay by doing a reverse handstand and jumping back to his feet. It's undermined a little by the obvious pain that Ranma is in upon standing up, but the fact he is still in fighting condition after a blow like that makes his Super-Toughness very much a matter of fact.
The anime version of the Martial Arts Takeout Race has one for Akane: as the rearrangement of events means Shampoo isn't here, the anime replaced her with Canon Foreigner Kaori Daikoku, who in the context of Martial Arts Takeout is just as formidable as Shampoo and even more violent... And Akane actually holds her own without Ranma to distract her. Only when Kaori busts out one of her secret techniques, which lets her grab Akane by the neck with a rope made of ramen noodles, is Ranma forced to intervene to set Akane free and give her a chance to run for the finish line. Speaking of which, at the final length of the race, Kaori manages to sprain Akane's ankle from afar by hitting it with a chopstick thrown line a dart, but Akane fights on past the pain and limps her way to the finish line, managing to get her bowl of ramen over the finish line just ahead of Kaori.
Kaori herself deserves some credit; even after Ranma turns into a girl to defend Akane, she keeps on fighting. Not even Ranma-chan wrapping herself around Kaori's legs, forcing her to literally crawl for the finish line, stops her from giving it her all, and she comes within a noodle's width of winning.
The simple fact that when presented with a choice between curing himself or saving Akane, Ranma doesn't hesitate to choose Akane over a cure. In the manga's finale, he doesn't even hesitate to smash the Jusendo pipes in his desperation to save Akane's life. In the finale of Non-Serial Movie 2, he gets a similar sequence where he blows up the masculinizing spring of Togenkyo rather than risk Akane falling into it, even though Akane herself pleads with him not to do so and to think of his cure.
Kuno beating Ranma while under the effects of the Nekoken by throwing a shredded bokken should be just funny... Until one reads the entire manga and realizes that he was the only one to do it. Everyone else facing Ranma under the effects of the Nekoken took the direct approach and fought a monstrously strong opponent, but Kuno just treated him like a cat and claimed victory without breaking a sweat. Made all the more impressive by the fact Kuno is normally portrayed as just being an idiot.
Shampoo gets one at the start of the manga version of the Martial Arts Takeout Race. When approached about having Shampoo compete in the race, Cologne brags about her great-granddaughter's skill and proceeds to demonstrate... by throwing daggers at Shampoo, who is currently facing away from her to deliver an order. Without even looking, Shampoo throws her order into the air, uses her tray to deflect the daggers back where they came from (leaving the representatives Pinned to the Wall), catches the falling order without spilling a drop, and then calmly walks over to them to deliver their order. And she treats the entire stunt as being no big deal.
The "fight" between Nabiki and Kinnosuke Kashao to make each other spend even just ten yen is mostly funny... Up until near the end, where Nabiki completely defeats Kinnosuke's attempts at making her spend money:
He brings in some girls collecting money for charity. She gets them to pay her.
From the start he had modified the plane they had rented so that at one point it would stall mid-air and the engines would resume working only if she put ten yen in a coin collector. She had already switched his parachute, and offered to sell it back to him for ten yen.
Since Kinnosuke is so miser he'd rather fall down from a plane than pay her, he smashes on the ground... So she grabs the puppet he insists is his butler and, using some ventriloquism, has it give ten ten yen to call the hospital from a pay phone. Nabiki would have won then and there had she not called the free emergency number out of her own misery.
After the previous error, Nabiki declares she's unworthy to be his fiancee if she makes such foolish errors, so she breaks up... And keeps the coin as consolation money, winning the battle of wits (and slamming him with all the accrued debt) while also he's actually worth just ten Yen.
