- Pretty much the whole series. Ranma 1/2 is about a boy who has been cursed to turn into a girl when doused with cold water and back into a boy when doused with hot water. The ridiculousness gets even funnier when it's noted that Ranma has a legion of women who are attempting to marry him for one reason or another and a ton of jealous, angry guys that are trying to kill him for it when in fact he is, surprisingly for a harem manga, a Chaste Hero. This is not to mention that everyone in the universe is humorously insane in one way or another, which further adds to the ridiculousness and hilarity of the situations.
- Upon learning of Ranma's curse Ukyo has fun turning him into a girl and back, often between shots. It's refreshing seeing one person take the transformation so lightly and having no problem pouring pot after pot of hot and cold water onto their fiance.
"This is fun no matter how many times I do it."
- "Saotome-Anything-Goes-Martial-Arts-Final-Attack: ready, set, RUN AWAY!"
- Made even funnier by Ryoga standing stunned for a few seconds before giving chase and Akane's commentary.
Akane: And you call yourself a martial artist!
- Another point to this one is how Genma's voice-over initially makes it sound like some technique requiring lots of discipline and skill... then Akane sums it up in the most deadpan voice possible:
Akane: In other words, run away until you can think of something better to do.
- What Soun does to Ranma when they learn how he's willing to reverse Akane's Laser-Guided Amnesia. It involves Ranma being beaten up, since Shampoo asked him to take revenge for her against "girl Ranma" (She didn't know they were the same person), and since Ryoga refused to help... he beats Ranma up. While crying Berserker Tears and screaming "you're an excellent person, Ranma! You love Akane so much you're willing to do that for her! Thank you, Ranma! THANK YOU, THANK YOU!"
- Pretty much any Soun reaction shot, but his expression the first time he sees Mirror Ranma(in a fetish apron!) is a Funny Moment among Funny Moments. Especially contrasted to his serene face earlier on the page.
- "Hey, look! Every jerk in the school is in the same place!" "There's only one thing to do now..." "BURY THEM!"
- When Cologne is in a sinking boat with Genma (who is a panda at the time) she hits him and tells him to do something. Hitting him causes all his signs to fall out of his... Er, pockets and Cologne promptly uses them to build a new boat.
- In a three-legged race with Ranma, Akane, Mouse, Shampoo and while paired up with Ukyo, Ryoga starts running the wrong way from the starting line. The opposite direction in fact, to the one being taken by every other contestant and his partner who was understandably upset with him for being such an idiot and making them both fall over. Of course Ryoga ends up getting so lost that he wins the competition anyway, by winding up at the finish line from the opposite direction.
- In the same episode, Ranma teams up with Akane during the race. Akane is flattered that he finally chose her for a partner, but Ranma merely wanted "the brute strength of an Akane." It doesn't end well for him.
- When Ranma is challenged to a ice-skating fight, Ryoga mocks him. Ranma of course won't stand for it and challenges Ryoga to solve it in the ice. Both laugh confidently as they prepare and walk up to the ice... only for them both to fall as soon as they step on it.
- In the anime's third season, a magical mishap sends Ranma, Akane, Shampoo, Genma, Soun, Cologne and Happosai back in time and across in space to when Happosai and Cologne were teenagers in China. We have Happosai vowing to teach his younger self to be good, Happosai wondering in horror that if he was this much of a pervert at eighteen; then what the hell is he now?!, the dumbfounded shock when everyone discovers that the gorgeous blue-haired girl is actually Cologne's younger self...
- Happosai as "Santa" finally having a conscience moment and giving his too-innocent-for-their-own-good "followers" the advice of doing good deeds...and on prompted for the kind of good deeds they should do, literally exploding from the strain.
- A good number of the chapters that feature Principal Kuno qualify.
- The Fishing Rod of Love arc is one big Crowning Moment of Funny. When Takahashi is on her game, she is on her game.
- The following:
Akane: Ranma, you do know what Romeo and Juliet are to each other, don't you?
Ranma: Father and daughter, right?
- In chapter 7, Ranma pouring boiling water on a dumbfounded dog.
- Ranma tells Akane You're Cute When You're Angry and a while later she looks in a mirror, and thinking on Ranma's words, goes to smile... at which point Ranma pops his head in and asks if mirrors make her smile or if she's just testing her cheeks. She punches him out.
- Ranma commenting on Akane's Panty Shot when he gets a look under her skirt which results in her kicking him.
- Ranma in female form convincing Ryoga she was actually his sister born while he was lost. Made even funnier because Akane saw through the disguise with no problem but ended up being fooled because she didn't think that Ryoga could be that naive.
- The ending of Bathhouse Battle. How did Happosai not see it coming? Then again, he may not have expected Ranma to sink that low to get revenge on him...
- Also "I don't trust you, you'll splash me from behind." "Aww. I'll just splash you from in front!"
- Ranma who starts to use "Nekoken" after being exposed to too many cats, bursts into the school gym and attacks Kuno easily shredding the ground, and his kendo wooden sword. Kuno catching wise, gets Ranma to chase after the shredded sword, and declares victory.
Kuno: Feh. The coward has turned tail and ran.
- Episode 87: "Oh yeah? You and what sense of direction?"
- "Oh uh..wait a minute....dont break-aaaaaaaaaaaaaaaaaaaaaaahhhhhhhhhhhhh!!!!!!!!"
- Nabiki after finding out Akane was home the whole time and not missing and she spent the whole night looking for her. "I'm cutting school today."
- Everyone acting grossed out and falling over after Akane offers them some of her pot stickers.
- Ranma, after being offered some of Akane's cooking. "Akane? You wouldn't mind running away again would ya?"
- In one of the earlier episodes Nabiki pours water on Ranma while he's sleeping to change him into a girl so she can take some pictures for Kuno and then turns her back. After Ranma wakes up he panics when he sees the water beneath him and thinks he wet the bed.
- Akari explaining why she'd only date someone who can defeat Katsunishiki.
Akari (crying lightly):"My grandfather said, before he died..."
Akari's Grandfather (flashback):"Akari, find a strong man to marry. I won't allow you to marry any man who can't beat Katsunishiki."
Akari (gesturing to old man lying next to her):"This is my grandfather."
Ranma:"Well, he certainly did say it before dying."
- In one arc, Pantyhose Taro plans on dousing Happosai with water from the Spring of Drowned Pious Man. However, the Tendo Dojo recieves a call that Taro took the wrong water from Junsenkyo.
Ranma: If he turns into a bug or a snake, we could just flick him out the window.
Soun: If he turns into a tiger, he won't be able to steal underwear...
Genma: If he turns into a monkey, he won't be able to do anything but steal underwear...
Apparently, he'll turn into...twins
- In episode 34, Ranma tries to infiltrate the girls' locker room to get to the Spring of Drowned Young Man beneath it. As soon as he opens the door he gets splashed with hot water from a kettle above the door, which was to meant to keep Happosai out.
- When the guide explains that Panthyose Taro's curse comes from the "Spring of Drowned Ox-Riding, Crane & Eel-Carrying, Yeti". This curse is so absurd that even other Jusenkyo-cursed characters are shocked.
- One time, Genma answers the phone...as a panda. One Beat Panel later...
Ranma: So why'd you pick it up in the first place?
- The one serious battle between Ranma and Cologne in the manga, during the Watermelon Race. At one point, Cologne stands up over the sea, to everyone's shock. Soun, the only one not shocked, explains that a master can stand still and walk on just a small leaf... Then we see what she was actually standing on:
"It's a shark
- In the final chapter of the Mushrooms of Time arc, Akane catches chibi-Ranma picking on a then smaller Ryoga. How does Akane respond? She gives Ranma a spanking!
- The witnesses' reaction to learn about Taro having been washed into the "Spring of Drowned Ox-Riding, Crane & Eel-Carrying, Yeti". The spring is so absurd even they can scarcely believe it.
- This dry line from Kasumi, about Akane, is classic: "She's really a very sweet girl. She's just a violent maniac."
