History Funny / HarryPotterAndTheHalfBloodPrince

* Specifically, the comparison between Ron and [=McLaggen=] handling their [[DoesThisRemindYouOfAnything broomsticks]].
** '''Ginny:''' [[BigShutUp SHUT IT!!!]]

--->'''Lavender:''' I happen to be his girlfriend!\\
'''Hermione:''' I happen to be his... friend.[[note]] And future wife.[[/note]]

'''Harry''': [[CaptainObvious But I]] ''am'' TheChosenOne.\\

-->'''Ron:''' Final score was three-hundred-and-twenty to sixty.
** And Harry's response.
--->'''Harry:''' [[SarcasmMode Brilliant! Really brilliant!]] When I get hold of [=McLaggen=]--\\

-->Slughorn's watery eyes slid over Harry's scar, this time taking in the rest of his face.\\

"My mother's eyes, yeah." Harry had heard it so often he found it a bit wearing.

-->'''Harry:''' I'll just take a mouthful. Two or three hours should do it.
-->'''Ron:''' It's a great feeling when you take it. Like you can't do anything wrong.
-->'''Hermione:''' ''(laughing)'' What are you talking about? You've never taken any!
-->'''Ron:''' Yeah, but I ''[[PlaceboEffect thought]]'' I had, didn't I? Same difference really...

* When Fleur at first tells Mrs. Weasley that Bill will still love her after he was attacked by Greyback, and then when she does understand what Mrs. Weasley was inferring, raves about how she doesn't care about how Bill looks and that she's "Good looking enough for the both of [them]".

'''Snape:''' You just... ''know.''

* Dumbledore playfully scolding Harry for not following the Ministry's idiotic advice leaflets, and making sure he was an imposter, by asking his favorite type of jam ("raspberry, by the way.") Then he adds that if he ''were'' a Death Eater impersonating himself, learning his favorite jam types would've been the first thing he'd do.

'''Hermione:''' ''(gives Harry a scandalised look)''

'''Ginny:''' A Pygmy Puff, but I didn't say where.\|

-->'''Vernon:''' WILL YOU GET THESE RUDDY THINGS OFF US?
-->'''Dumbledore:''' Oh, I'm sorry. (Vanishes the glasses) But it would have been polite to drink them, you know.

* The fact that a) the Order's reaction to Hagrid getting to care for Buckbeak is literally just to rename him "Witherwings" so that the Ministry won't guess it's the same hippogriff and b) ''that it actually works.'' YMMV if this is RefugeInAudacity or if it's just one more instance of wizardry's complete lack of anything resembling common sense, but either way, it's hilarious.
** One wonders if perhaps the Order could have hidden Sirius in plain sight just by giving him a pair of glasses and a different name.
*** Roonil Wazlib, perhaps.

-->'''Madam Pomfrey:''' No more than six visitors at a time!
-->'''George:''' Hagrid makes six.
-->'''Madam Pomfrey:''' ''(clearly having mistaken Hagrid for an entire group of people)'' Oh...yes..

--->'''Ginny:''' You'd think people had better things to gossip about. Three dementor attacks in a week, and all Romilda Vane does is ask me if it's true you've got a hippogriff tattooed across your chest.
--->''(Ron and Hermione both bust out laughing)''
--->'''Harry:''' What did you tell her?
--->'''Ginny:''' I told her it's a Hungarian Horntail. Much more macho.
--->'''Harry:''' Thanks. And what did you tell her Ron's got?
--->'''Ginny:''' A Pygmy Puff, but I didn't say where.
--->''(Ron scowls at her; Hermione laughs even harder)''

** The [[DeathGlare enraged glares]] that every girl in the main hall gives to Harry when he goes to Slughorn's party with [[CloudCuckoolander Luna Lovegood]].

* Before arriving at Hogwarts, Ron purchases an enchanted quill from Weasley's Wizard Wheezes to help with his spelling, but only a few chapters later, he's complaining about how it's malfunctioning and actually making his spelling ''worse''. Much later, after Harry tries the Sectumsempra curse he found in his used copy of ''Advanced Potion-Making'' on Malfoy, Snape uses Legilimency to read Harry's memories and orders Harry to bring him the book. Not wanting Snape to take the book away, Harry hastily asks to borrow Ron's, and clearly didn't check the book before handing it over.

* Harry hastily procures Ron's book:

** The best part is how much of a BrickJoke this is.

*** Also, Snape's line "I understand what a nickname is" becomes even funnier (and maybe a little harsher) when we remember "Snivellus."

* When Ron is under the Love Potion, Harry immediately brings him to Slughorn to get him fixed up. Slughorn is surprised that Harry (who's done quite well in his Potions classes) would need the help. Harry said it was an emergency. Slughorn takes one look at Ron's dopey face and quickly agrees.
* 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.
* The face Ron makes as the Love Potion wears off goes from vague delight to dull horror.
