History Funny / HarryPotterAndTheHalfBloodPrince

** One of these lines is said by Ginny, which (given her previous experiences) makes it borderline BlackComedy.

** Particularly funny since Hermione would go out with Ron in an instant if he just asked her outright.

** Dumbledore delivers that last line in the most airy, cheerful manner possible, like he didn't just witness an angsty teenage romance drama ''or'' like he's seen similar scenes so many times during his years at Hogwarts that he's no longer fazed by them.

*** FridgeBrilliance when you consider the reveal in ''Deathly Hallows'' that Snape [[spoiler:Knew what it was like to have your romance go horribly wrong during your school years]].

** Harry wonders who in their right mind would ever allow Luna to commentate Quidditch. It's ''[=McGonagall=]'' that chooses the Quidditch commentators. Indeed, shortly after this, we're told that [=McGonagall=] is looking as if she's having second thoughts about the appointment. Which makes one really wonder if [=McGonagall=] was feeling okay on the day she chose the commentators.

* Hermione thinks that the handwriting in the book looks like a girl's. Turns out near the end of the book that said "girl" is Severus Snape.

-->'''Ginny:''' [[LampshadeHanging He's covered in blood. Why is he always covered in blood?]]\\

* Flitwick's punishment to Seamus:

** The students first seeing the love potion and how they just, sort of, ''float'' toward it.

** Harry gives a quick nod to [[Film/HarryPotterAndTheChamberOfSecrets Chamber of Secrets]] when Slughorn asks if Aragog had any family. Harry responds with a casual "Oh, yeah.", obviously remembering him and Ron almost being eaten by Aragog's children.

** Harry lets slip a little laugh and responds "I didn't like her, either".

* When Harry and Dumbledore go into Slughorn's memory of Tom Riddle asking him about Horcruxes, Harry, who has plenty of experience of getting information from those reluctant to spill the beans, is actually ''impressed'' by Riddle's skill, noting that he's watching "a master at work".

-->“Yes, Harry, you can love...” said Dumbledore, who looked as though he knew perfectly well what Harry had just
refrained from saying.

* Hermione thinks that the handwriting in the book looks like a girl's. [[spoiler:Turns out near the end of the book that said "girl" is Severus Snape.]]

* A small one during [[spoiler:Dumbledore's funeral]] when Umbridge sees Firenze and immediately legs it to a seat as far away from him as possible.

* After Slughorn finally agrees to Dumbledore's offer, Dumbledore starts humming happily.

* After Luna fixes Harry's broken nose:
-->'''Harry:''' How do I look?\\
'''Luna:''' Exceptionally ordinary.

* In the Slug Party:
-->"What's this I'm eating again?"\\
"Dragon Balls.''
** [[IAteWhat Also what happens next:]]
--->'''Snape:''' ''(sweeps in to find Harry and Cormac)''\\
''(Cormac [[VomitDiscretionShot vomits on Snape's shoes,]] then [[OhCrap wordlessly stands up straight]])''\\
'''Snape:''' You just bought yourself a month's detention, [=McLaggen=].
** Harry then tries to make a quick getaway but Snape cuts in without missing a beat:
--->'''Snape:''' [[DramaticPause Not... so quick]], Potter. ''(sweeps back out of the corner)''\\
'''Harry:''' Oh, sir, I really think I should get back to the party. My date...\\
'''Snape:''' ...could surely survive your absence another minute or two.
** Harry asks Snape how long Dumbledore will be away for. Snape gives brief pause before wordlessly wandering off.
** Hermione trying to duck her date, who she only brought because she thought it would annoy Ron. Her {{Adorkable}} actions are priceless. Meanwhile, Harry just thinks Ron and Hermione are idiots for dating other people to make the other jealous. You can just ''hear'' him become sarcastically done with the whole thing.
** When Hermione is offered a tray of hors d'oeuvres, she initially refuses until the server tells her that they give one horrible breath. [[OnSecondThought She takes a moment to consider before stuffing her face with them to try and ward off McLaggen.]]
* Ron [[MySisterIsOffLimits characteristically]] [[MomentKiller ruining a moment]] between Harry and Ginny at the Burrow on Christmas Eve. As Ginny feeds Harry a dainty mince pie from her plate, Ron sits heavily between them, and appears clueless to both their exasperated faces.
** He then offers them a plate of rather larger mince pies, which appear to have been made with somewhat less care than Ginny's. A nice bit of visual symbolism.
** Also before that. Mr. Weasley rather awkwardly and deliberately leaves the room as soon as Ginny arrives, seemingly invoking the LeaveTheTwoLovebirdsAlone trope.

* Before the above scene, Harry's reason for wanting to go to the Three Broomsticks was because he saw Professor Slughorn heading that way. During this scene, Slughorn stumbles upon Professor Flitwick and invites him for a drink. Flitwick, in a moment of humorously uncharacteristic rudeness, makes up an [[INeedToGoIronMyDog an obviously fake "emergency choir practice" excuse]] and immediately hurries off.
** In the following scene, Hermione is swaying between Harry and Ron as if she'd partaken of slightly more Butterbeer than was good for her. This is a light moment before the MoodWhiplash of Katie Bell being cursed by the necklace.

* Harry under the influence of Felix Felicis:
-->'''Prof. Slughorn:''' Harry!\\
'''Harry:''' ''(same annoyed tone)'' Sir!
** Harry during the whole Felix Felicis scene is funny. His uncharacteristically peppy attitude, [[LargeHam steals the entire scene]] (especially when he enacts how a giant spider's pincers work).
** Harry gives a quick nod to [[Film/HarryPotterAndTheChamberOfSecrets Chamber of Secrets]] when Slughorn asks if Aragog had any family. Harry responds with a casual "Oh, yeah.", obviously remembering him and Ron almost being eaten by Aragog's children.
** Daniel Radcliffe's reading of the line "Personally these plants always kind of freak me out. Hmm."
** Right after taking the Potion, Harry's alarmingly happy "Hi!" to a random bloke.

* Luna's adorable [[http://vignette4.wikia.nocookie.net/harrypotter/images/8/8f/Luna_Lovegood_on_her_homemade_Lionhead_hat.jpg Gryffindor hat]].

* Harry tells Ron he will take him to see Romilda Vane, but instead takes him to Professor Slughorn. Ron hugs him thinking he is actually Romilda because he has no idea who she actually is.
* [=McLaggen=] flirting with Hermione. ''By licking his fingers.''
* Harry coming back to the feast after being sneak attacked by Malfoy.
-->'''Ginny:''' [[LampshadeHanging He's covered in blood. Why is he always covered in blood?]]\\
'''Ron:''' At least it looks like it's his this time.
** One of these lines is said by Ginny, which (given her previous experiences) makes it borderline BlackComedy.
* [=McGonagall's=] {{memetic|Mutation}} exasperation upon discovering Harry, Ron, and Hermione are caught up in the latest crisis yet ''[[WeirdnessMagnet again]]''.
-->'''[=McGonagall=]:''' Why is it, when something happens, it is always ''you'' three?\\
'''Ron:''' Believe me, Professor. [[LampshadeHanging I've been asking myself the same question for six years.]]
* Another pretty funny [=McGonagall=] moment comes after she catches Harry and Ron goofing off in the hallway and directs Harry to Potions class:
-->'''[=McGonagall=]:''' Take Weasley with you, he looks far too happy over there.
* Price negotiations with Fred and George.
-->'''Ron:''' How much are these?\\
'''Fred and George:''' Five galleons.\\
'''Ron:''' How much for me?\\
'''Fred and George:''' ''Five galleons.''\\
'''Ron:''' I'm your ''brother.''\\
''(beat)''\\
'''Fred and George:''' ''Ten'' galleons.
** Also, Fred and George each have different expressions when they say that last line, both funny.
* Weasleys' Wizard Wheezes shop features an animated doll of Umbridge skating across a tightrope, squealing "[[TyrantTakesTheHelm I will have order! I will have order!]]"
** Bonus funny points: The only two people present the only time Umbridge said that were Harry and Hermione. Imagine ''Hermione'' of all people doing an Umbridge impression while recounting to the twins about how she got Umbridge off their back.
* When Harry and Dumbledore are about to leave for the cave:
-->'''Harry:''' But sir, I thought you couldn't Apparate in Hogwarts.\\
'''Dumbledore:''' Well, [[ScrewTheRulesIMakeThem being me definitely has its advantages.]]
* Specifically, the comparison between Ron and [=McLaggen=] handling their [[DoesThisRemindYouOfAnything broomsticks]].
** '''Ginny:''' [[BigShutUp SHUT IT!!!]]

* The scene where [=McGonagall=] is trying to direct everyone to their classes.
-->'''[=McGonagall=]:''' Mr. Davies, that's the girls lavatory.
* A rather subtle one, but Slughorn's face sports a quick "OhCrap" look when he accidentally rips off Aragog's pincer while trying to extract some of his venom. Right in front of a sobbing Hagrid, by the way.

* Slughorn's potions class has a few:
** The students first seeing the love potion and how they just, sort of, ''float'' toward it.
** Slughorn's pure giddiness at Harry's Draught of Living Death, happily exclaiming that a single drop would easily be enough to ''[[BlackComedy kill the entire class]]''.
** Harry and Ron fighting to see who will get the newer-looking Potions book in the cupboard, topped with Harry smacking Ron's book childishly with his own.
** Hermione's increasingly MessyHair as Harry finishes his potion much earlier than her.
** Continuing the films' RunningGag of Seamus BlowingStuffUp: during the Potions class, he looks down into his cauldron when it spontaneously explodes in his face, leaving him with an AshFace.
** Crabbe realising his [[EpicFail potion]] has melted the end off his stirrer.
** When Slughorn presents Harry with the Felix Felicis, the rest of the class are noticeably put out and reluctant to [[SarcasticClapping applaud him]], complete with disgusted looks on their faces.
** Harry is so excited to win the elixir, he immediately reaches for it; Slughorn gently bats Harry's hand away to finish his speech.
* Upon arrival in Budleigh Babberton, Dumbledore expects that Harry is probably wondering why he brought him there. Harry admits "Actually, sir, after all these years, I just sort of go with it."
* Snape being a magnificent, scene-stealing {{jerkass}}, as usual, after Harry accuses Malfoy of being a Death Eater:
-->'''[=McGonagall=]:''' That is a very serious accusation, Potter.\\
'''Snape:''' Indeed. Your evidence?\\
'''Harry:''' I just know.\\
'''Snape:''' You just... ''know.''

** Also the way that Snape just stares straight ahead during that scene. And the fact that he's there at all watching it.

-->"That's what she did, did she? [[WhatAnIdiot Idiotic woman.]] Never liked her.

** Harry wonders who in their right mind would ever allow Luna to commentate Quidditch. It's ''[=McGonagall=]'' that chooses the Quidditch commentators. Indeed, shortly after this, we're told that [=McGonagall=] is looking as if she's having second thoughts about the appointment. Which makes one really wonder if McGonagall was feeling okay on the day she chose the commentators.

* When harry suggests to Mr. Weasley to raid Malfoy Manor at King's Cross, Mr. Weasley's first reaction is to ask if he's about to find out where Harry, Ron, and Hermione ran off to back in Diagon Alley. When Harry sheepishly asks how he knew, Arthur's only response is an annoyed sigh.

** A meta example: JK Rowling said she was tired of writing Quidditch scenes and intended while writing for this match to be the last one featured in the series (which was fine by the actors and filmmakers, as they were tired of filming them). [[HilarityEnsues So she had Luna provide commentary to make it interesting.]]

* At one point when Professor McGonagall is giving directions, she at one point has to correct a ''very'' lost student:

* Slughorn's response to Umbridge calling the centaurs "Filthy half-breeds":

---> '''Hermione:''' Excuse me, I need to go vomit.
