'''General'''
----
* Yusuke. You gotta admit, that smart mouth of his always brings something funny.
* Kuwabara when he's making a fool of himself. [[ButtMonkey Poor dude]] but you can't help but find it hilarious.
* Anytime Yusuke, Kuwabara, and Hiei start arguing, with Kurama mediating, or anytime Kurama and Hiei sit back and make comments while the others are doing something, mostly because Kurama's one liners are hilarious, and he's the only person who can make fun of Hiei with impunity.
--> ''Hiei gives Kurama the stone his mother gave to Yukina, with the intention that Kurama gives to Yukina instead of Hiei''
--> '''Kurama:''' I'm sorry, I can't accept this Hiei. You know I respect our long friendship... but... I just don't like you in that way. ''Hiei's reaction is a straight up Crowning Moment''
* A lot of Koenma's random quotes, as well as his interactions with Ogre (who wavers between BumblingSidekick and OnlySaneMan).
--> '''Koenma:''' ''(as a casual introduction)'' "Hello. I'm Koenma. I'm very cool."
* Hiei has his moments too.
--> [[quoteblock]]"I know as much of games as I do of hugs and puppies, and care for them even less. Wake me for the end of the world." [[/quoteblock]]
--> '''To Botan:''' ''(about telling Yukina's secret)'' "You talk, you die."
* Practically any time Jin opens his mouth past his initial appearance, especially in season four. In fact, the anime seems to use Jin to make a point that scenes during that season are getting serious when they show him actually not talking for a change.


'''Season 1'''
----
* In the dub, Yusuke's reaction to finding out the guy giving him his ordeal looks like a toddler. The response to said teasing is also hilarious.
--> Actually, I'm proud to say that in addition to knowing the greatest secrets of the universe, I'm also quite potty trained.
* Episode 4 after Keiko got Yusuke's body out of the burning house. When Kuwabara looks inside the blanket to see Yusuke's corpse, the look on his face was priceless.
* Yusuke using the body of a high school girl to kick the butts of a gang of bullies as Kuwabara was studying for the "test".
* Yusuke trying to get Keiko to recognize him in Kuwabara's body and finally settles on a...''unique'' version of "Guess who?". It gets even better afterwards, where Keiko is hanging on Kuwabara's body as Yusuke's spirit leaves it... Kuwabara's bafflement just makes it.
** Even funnier is when Keiko figures out that Yusuke's not possessing that guy's body anymore, and he's still hugging her. She freaks out and slaps him, before quickly apologizing and running away. Kuwabara just looks completely confused and mutters "No, it's fine. I probably deserved it".
* When Yusuke finds out about Eikichi:
-->'''Thug 1:''' ''(to Kuwabara)'' "You're pathetic."
-->'''Thug 2:''' "You may as well give us your backbone too."
-->'''Yusuke:''' ''(thinking)'' "Whoa! This Eikichi must be something special for Kuwabara to sink that low!"
-->'''Thug 1:''' ''(pulls a cat out of a bag)'' "I just can't believe you're doing all of this for a retarded fuzzball."
-->'''Eikichi''' "Meow!"
-->'''Kuwabara:''' "DWUAH! AHHH! EIKICHI!"
-->'''Yusuke:''' Dwuah?! ([[FaceFault face faults]])
* The sequence after Rando [[HoistByHisOwnPetard shrinks himself.]]
--> '''Rando:''' ''SWAMP ALGAE?!''
* Kuwabara insists on not helping Yusuke in rescuing Yukina--until he sees the Spirit World video, showing a surveillance footage of Yukina held prisoner. This changes his mind and wants to go help Yusuke, despite the contrary. Kuwabara "accuses" Yusuke of making stuff up despite what Kuwabara said earlier. And then Shizuru shows up in Kuwabara's room.
** For the record, Kuwabara thought that they were going to watch an X-rated show.
** It gets even better. Kuwabara insists that they are attached by the RedStringOfFate and it will lead them to Yukina, not to mention his "[[MundaneMadeAwesome Headband of Love!]]"
*** Or his reaction when one of the demons in the Triad [[FelonyMisdemeanor cuts off said "Headband of Love"]].
** Yusuke telling Botan that (thanks to Kuwabara seeing Yukina and instantly switching his affections to her) Kuwabara seems to have moved on and forgotten about her... Botan says that she's brokenhearted for being replaced
* When finding out the demon Miyuki is actually a transvestite... Yusuke's deadpan expression matched with this quote:
--> '''Yusuke:''' [[WholesomeCrossdresser "The family jewels have not been stolen."]]
** The manga has a chibi 3-part doodle showcasing how Yusuke discovered that Miyuki is a transvestite. The first part shows Yusuke grabbing Miyuki chest and discovering it was padding. The second part shows him grabbing Miyuki between the legs and discovering that "she" was packing [[BiggusDickus quite a piece]]. The third bit? Shows Yusuke PUKING as he runs away from "her".
* Manga-only: the fake Yusuke and Kuwabara. Two youkais who decided to take them down by disguising as them and causing trouble, forcing our heroes (temporarily crippled by the aches from the battle against the Four Saint Beasts) to fight the whole gang of the rival Kasanegafuchi junior high school, and then jump the survivors with the help of a gang of powerful youkais. This ends badly... For them.
** The battle between Yusuke and Kuwabara and the delinquents is interrupted by Kurama imitating [[Anime/SailorMoon Tuxedo Kamen]], who then points out the real culprits
** The fakes are still sure they can win, and summon their gang... Who don't show up. They turn to see what happened... And have an absolutely ridiculous OhCrap when they see Hiei ''complaining they hired the weak youkais he just annihilated''
** When the Kasanegafuchi guys are finished with them, the fakes are lying on the ground [[AmusingInjuries beaten up in a funny-looking way]], [[NakedPeopleAreFunny naked]] and with their clothes being burned as the finale of their HumiliationConga
** Yusuke is thanking Hiei for the help, and moves to shake his hand... Only for Hiei to place a VHS in it, announce it was Koenma's instructions for the next case (Yukina's rescue) and leave while celebrating that with this his sentence has expired.


'''Season 2'''
----
* When Hiei greets Yusuke before the preliminaries of the Dark Tournament both moments were this...though the edited Toonami version of the dub actually managed to be funnier than the uncut version!
--> ''(After Hiei attacks Yusuke with his sword, Yusuke dodges the slashes at rapid speed, Yusuke manages to finally catch the blade.)''
--> '''Uncut Dub Version Yusuke:''' "Damn Hiei, this how you say hello now?"
--> '''Edited Dub Version Yusuke:''' "Hiei, I see you've been working on your people skills."
* When they are all on the boat, heading to [[NamesToRunAwayFromReallyFast Hanging Neck Island]] for the Dark Tournament, They announce there will be a Preliminary match on the ship. The "Masked Fighter" volunteers to fight all the other demons on the ship in a battle royal. Kuwabara insists against it, saying they don't know jack squat about the guy. Saying that "he might lose" then what would they do? This following exchange happens:
--> '''Hiei:''' ''([[SlasherSmile smirk]])'' "If that happens then we'll just have to kill everyone on board. We'll say we're the right team and no one will complain."
--> '''Kuwabara:''' ''(creeped out expression then says in a complete deadpan)'' "You didn't have many friends growing up, did you?"
** Made funnier when the Masked Fighter [[CurbStompBattle wins the battle royal in a single attack]] and it turns out ''all the other teams had Hiei's idea''.
* Chu. Just...Chu.
--> "What did you say!? 'The substitutes is just a stinkin' drunk'?! Take that back! [[ITakeOffenseToThatLastOne I am not a substitute!]]"
** Also, a funny moment when Chu first shows up--he's staggering around the ring and acting like a clown, but Shizuru points out that there's something beneath his clownishness that seems highly dangerous. Keiko says that everyone must be worried and at the edge of their seats... [[DescriptionCut cut to Koenma blissfully stuffing his face.]]
---> '''Koenma:''' [[NonSequitur "I love squid!"]]
* Yusuke vs. Jin had quite a few of these moments... mostly from [[EnsembleDarkhorse Jin]].
--> '''Jin:''' "I thought I was crazy! But you take the prize Urameshi! The hell was that?! You don't just make bombs go boom in your face!!"
** Made even funnier by Jin's tendency to speak faster than [[BenCroshaw Yahtzee]]. Don't let the punctuation fool you, there are no breaks between those sentences.
* In-between rounds at the Dark Tournament, the reflection of Yusuke's inner self turns out to be... a little blue and fuzzy penguin. "Puu!"
* When Puu hatches... everyone's reaction to it. THE WHOLE GANG! This troper's personal favorite was Hiei's deadpan comment about the adorable creature.
-->'''Hiei:''' "Gift from your girlfriend?"
-->'''Yusuke:''' "No! ''That'' I could get rid of!"
** The lines from the dub are also hilarious. Hiei was so dry and deadpan he didn't even change his tone when he switched his attention from Kuwabara to the cute creature on Yusuke's head, and he doesn't even pause between sentences.
--->'''Hiei:''' [[DeadpanSnarker Yes, well I'm sure your minty fresh breath was well worth the wait]]. ''(looks at Yusuke)'' [[TheComicallySerious What is that ridiculous appendage growing out of your head?]]
--->'''Yusuke:''' It's just a puberty thing, okay?!
* A face off for the ages! Kurama vs. Kuwabara vs. Hiei... in [[MundaneMadeAwesome Rock, Paper, Scissors!]]
* Yukina's last line about the ShipTeasing of Yusuke and Keiko during an intermission for the Dark Tournament. Having barely any experience with the outside world, her confusion about the subject is understandable but hilarious.
--> '''Yukina:''' Have fun with the birds and bees!
* The Genkai vs. Suzuki fight.
** This troper kept giggling at Kurama's reactions during the whole fight. For the usually unflappable Kurama to look utterly bewildered was a sight to behold.
*** The gem for this troper was Genkai's comments on the deal. Specially her comment in such a annoyed and unimpressed tone..."Fruitcake!"
* [[DeadpanSnarker Kurama]] + StealthInsult = Lolwin!
--> "And to think one day they could be in-laws."
* Hiei's [[TheComicallySerious Comical Seriousness]] makes for a few good ones:
--> '''Hiei:''' "If I wake up and find we've lost, I'll kill you... all..." ''(collapses)''
--> '''Yusuke:''' "That's Hiei for you. He faints, but he still makes time for threats."
* The scene where Kuwabara [[spoiler:revealed he had faked his death]] at the end of the Dark Tournament saga left this troper in stitches, especially since it happened immediately after an epic {{Wangst}} moment by Yusuke.
--> '''Kuwabara:''' "Reporting for duty, Captain Faker! That's me!"
** This is swiftly followed by Yusuke proceeding to beat the everloving crap out of Kuwabara. Even ''Hiei'' [[NotSoStoic is disturbed by the beating Yusuke gives Kuwabara!]]
--->'''Koenma:''' "Yusuke, teach him anymore and you'll ''actually'' kill him. That's kinda against the point, isn't it?"
* Koto and Juri tend to have several silly moments over the course of the Dark Tournament Arc.
** [[http://www.youtube.com/watch?v=AdyI-KP2E9s "Let's find you a man!"]]
* Near the end of the Dark Tournament arc, Keiko suffers a severe case of [[HeroicBSOD PTSD]]. Yusuke's solution is to '''[[CrossesTheLineTwice literally]]''' slap some sense into her. [[http://www.youtube.com/watch?v=72vqFlUJjWk Her reaction was legendary.]]
* All four of them talking about what they'll do when they get back to normal life after the Dark Tournament. Hiei's [[TheComicallySerious deadpan]] really kills it:
--> '''Yusuke:''' Skipping detention.
--> '''Kuwabara:''' Video games!
--> '''Kurama:''' My human mother.
--> '''Hiei:''' Various crimes.
* Genkai when she greets Yusuke [[spoiler: after the Dark Tournament]].


'''Season 3'''
----
* Botan and [[ThoseTwoGuys those three guys]] conclude that Yusuke and Kuwabara must have been an [[LikeAnOldMarriedCouple old married couple]] in a past life. So... "[[ImagineSpot Who was the husband and who was the wife?]]" Among ''many'' others.
* Yusuke storms out of his house, because Sensui is endangering the world and his posse is MIA (Kurama), [[ScrewThisImOuttaHere screwing it and getting out of there]] (Hiei) and at a [[BlandNameProduct Megallica]] concert (Kuwabara), yelling that he's going to the arcade to play video games. [[VictoriousChildhoodFriend Keiko]] is all concerned, but [[OldMaster Genkai]] shakes her head and says not to worry, because she's sure Yusuke has sensed Kuwabara's about to awaken and manifest a new power, and has gone to look after him. [[GilliganCut Cut to Yusuke angrily beating a video game]]. Later, we get a scene of Genkai throwing him out on his ass, screaming at him for not going to protect Kuwabara.
--> '''Yusuke:''' "I SAID I was going out to the arcade Ms. Senile!"
* When Kurama, Kuwabara, and Botan are looking for Hiei, Botan whips out a "demon whistle" which will make demons come to it like a dog whistle. The range was practically the whole city. When Botan blows it, it turns out Hiei was sleeping in the tree forty feet away.
** The clincher was the way this was revealed: as a FunnyBackgroundEvent with Hiei falling head first from the branch he was sleeping in.
** There's also Hiei's BlatantLies that he was actually searching for the source of the sound so he could kill it.
* When Yusuke finds out Koenma knew the identity of their enemy all along, he decides to call him on the briefcase videophone:
-->'''Yusuke''': EARTH TO TODDLER BITCH!!!
* When Sensui calls for Makihara:
--> '''Mitarai:''' "That's Gourmet."
--> '''Yusuke:''' "Oh great, does he cook?"
* After Yusuke [[spoiler:comes back to life thanks to his demonic genes]], he claims to be an evil and powerful demon in front of the Spirit World's Special Defense Forces [[spoiler:who were sent to destroy his body and prevent his revival]]. The characters are quite convinced until he reveals that he's kidding.
* This troper found it very funny that in the uncut dub Kazuya[[spoiler:, one of Sensui's {{Split Personalit|y}}ies,]] gets to call Yusuke a "little shit" and tell Sensui, "Don't pussy out now!" but still has to follow up the latter with, "Not when it's about to get so [[GoshDangItToHeck freakin']] fun!"
* When Yusuke and Sensui relocate during their fight [[spoiler:in Demon World]]:
--> '''Yusuke''': Alright pal, it's just you and me. Well, [[SplitPersonality you and you and you and you and you and you and you]] and me.

'''Season 4'''
----
* When Yusuke confronts Yomi, Kurama and the Dark Tournament fighters have a silent discussion by writing out their words, since Yomi would probably hear their whispering. At one point, Rinku holds up a paper with nothing but [[VisibleSilence Elipses]] on it. Chu {{Dope Slap}}s him saying you don't have to ''write'' a dramatic silence out. Then, when Kurama asks the others whose side they would be on if it came down it it, nearly every one of them held up a single card reading "YUSUKE" (Rinku: "Did you even have to ask?")... Except Shishiwakamaru, who holds a paper reading "Undecided". (The Beautiful) Suzuki comes up and changes the paper to supporting Yusuke. Even more amusing in the dub, where the voice actors provide translation for the messages.
* How about Yusuke's "diplomatic" approach to Yomi in the Three Kings saga?
--> '''Yusuke:''' [[spoiler: "YOMI!! YOU SON OF A BITCH!! YOU HEAR ME?! I'M COMING! SO BOIL UP A KETTLE OF TEA!!"]]
** Made into a BrickJoke when Yomi arrives to meet Yusuke in one of his chambers. An assistant arrives with him, [[spoiler: and presents Yusuke with the tea he asked for, bemusing Urameshi slightly]].
* The Dark Tournament fighters after Yomi ask Kurama how he helped them become so powerful and Kurama downplays [[TrainingFromHell Genkai's training]] as eating right and working out, so to speak. The fact that it's [[TheStoic Touya]] that actually starts the mouthing off just makes it even better.
* After the preliminaries of the last tournament end, a BigBadWannabe goes up to Yusuke and tells him that he's going to defeat him in the second round, Yomi in the third round, win the tournament and take over the Demon World. Is this where Yusuke fights and easily defeats him in the second round? Nope! The demon doesn't even make it past the opponent in the first round, who in turn goes on to lose to Yusuke (presumably fairly easily), [[spoiler:and Yusuke loses to Yomi, albeit barely]], showing just how much of a blowhard his would-be second round opponent is.
* "[[UnsettlingGenderReveal Is this your girlfriend, Kazu-san?]]" The manga is funny because Kurama gets all pissy. The anime is funny because he's so nonchalant, even when one of the girls bends over to stare at this chest. Just to make sure.
