Disclaimer: It's a pity but I don't own Ron, Hermione and Harry. They are actually the property of J.K. Rowling, surprising I know!
"No Ron, Larry the Snappy only arrived in power after the third goblin war had ended. He succeeded Derick the Demented after he passed away during an eating contest." said Hermione for the fifth time that night.
"After that came Twiddle-Dum and his brother Twiddle-Dee…" piped up Harry.
"Harry stop telling him nonsense!" snapped Hermione, banging her book on the goblin wars shut.
"Nonsense!" cried Harry in outrage. "Is that what you call my attempts at helping my friend in his studies?"
"Well, no, but…"
"It's true that I'm not as intelligent as you are but that doesn't mean I'm completely stupid! To hear you calling this nonsense is like hearing that Urg the Unclean was a hygiene maniac, or that the Brotherhood of the Magical Carrot Once Eaten By A Were-rabbit doesn't exist."
"Harry, the Brotherhood of the Magical Carrot Once Eaten By A Were-rabbit does not, in fact, exist." said Hermione with a long suffering sigh.
"It does exist, it says so in the Quibbler!" cried Harry indignantly.
"Well, the Quibbler is hardly…."
"And I won't let you say that the Quibbler is hardly the best source of information! If you recall, it was the only newspaper that wrote articles that weren't complete nonsense about Voldermort and me last year. Not to mention they are the only people brave enough to admit that the Crumple-Horned Snorkack exists!"
"Harry, the Crumple-Horned Snorkack is not real!" said Hermione a little annoyance.
"There are plenty of eye-witness accounts. Just because you're so narrow-minded you need to have everything shoved under your nose..."
"Harry, imitating Luna won't get you anywhere." said Hermione firmly.
The raven haired boy sighed and leaned back in his chair, pouting. Ron, who had been desperately trying to understand his friends' conversation, looked wildly between the two.
"Alright, so we stopped at Derick Demented dying in an eating contest…" said Hermione attempting to get back on track.
"I heard from Barnabas the Barmy, that Derick the Demented actually held the world record for the amount of sausages he ate at once. He managed to eat sixteen without choking on them." said Harry conversationally.
"Not that it would be very useful if he died from it…" mumbled Hermione.
"Oh, no! He didn't die from it! That was in the first eating contest of his reign. He died during the fifth. The contest was about eating whole chickens. I heard he choked on a bone. But, of course, all of that was after he went hunting with Bodrod the Bearded who was actually the son of the aunt of Derick the Demented's second cousin who was married to Ug the Unbearable's youngest brother, who was called Bidoc the Brave. Bodrod the Bearded wasn't Bidoc the Brave's son though, as the aunt of Derick the Demented's second cousin had an affair with her husband's best friend's uncle. But she also had an affair with the brother of the nephew of Ug the Unbearable's wife, who herself had a lot of lovers, such as…"
"Fine! We'll stop studying. Not like we could do much with all that rambling anyway…" snapped Hermione.
"Yeah, let's take you outside mate." said Ron with the air of someone taking care of an insane person, which Harry was not.
The raven haired boy smiled broadly.
"You know, if you didn't want to work, you should have just said so!" he told them while leading them out of the common room.
