Gryffindor have always been known for their incredible quidditch skills, loyalty and lack of respect for the rules. But the boy who gave all these characteristics a face was Sirius. But what is the measure of a true Gryffindor, that's what this story is-

"Would you listen to her?" Marlene interrupted, and very rudely so too. "She's making the story sound about as interesting as cardboard"
"Lighten up, Prankoholic!" said Dorcas.
"Why don't we take it from here?" Lily asked, although she wasn't really asking.
Fine if you want this fic to turn out all bananas then suit yourself!
"Well, why don't we introduce ourselves?" Lily suggested. "I am Lily and these are my friends Dorcas and Marlene, and were here to tell you a little story about a prat in our class-"
"Now Lily this story is for praising him for what he did in our first year!" Marlene pointed out.
"You mean sneaking into the girls' dorm and covering our faces with gum? Or that time when he made our shower spurt ketchup? Nope, I honestly won't miss him!" Lily crossed her arms and looked away.
"He's not dead but anyway. Our story doesn't begin with Sirius 'though" said Dorcas.
Music begins:
(Tune: Gospel Truth I)

Dorcas:
Back when we girls were new
And Gryffindor was down on its luck
'Cause Slytherin won every single match since our team sucked

Lily:
They played some nasty games
They made a mess wherever they aimed
Yet they broke every single rule, it was a bloody shame

Marlene: But then along came James!
Dorcas:He flew his Cleansweep 3
Marlene:He soared!
Dorcas:Showed those suckers who are we!
Marlene:And scored!
Dorcas:And on his own stopped Slyther's winning plans
All:And that's the quidditch truth
Marlene:The guy was in and that's how it began

Dorcas:
And that was his first match
James tamed those quaffles while in his youth
All:
Though honey it may seem impossible
That's the quidditch truth
Back in the common room life was neat and smooth as sweet vermouth
Though honey it may seem impossible
That's the quidditch truth

But halfway through the Hogwarts Quidditch tournament James had been viciously hit by a bludger and thus he couldn't play for the rest of the year. Therefore, they had had an audition for a new chaser and it turned out Sirius wasn't all without talent either. After another successful game for Gryffindor, Sirius was relaxing in the most comfortable chair in the commonroom while some girls were pealing grapes for him.
Professor McGonagall and Headmaster Dumbledore stopped by to congratulate him.
"You played well today" said McGonagall. "I saw it in you right when you were being sorted! I thought: Now there's a boy that is good at quidditch!"
"No you didn't" said Dumbledore, his mouth full of grapes. "You said: Now there's a boy who might suck all my blood out if I don't watch my step"
"You shut up now"
Anyway, the entire house all had a good time when suddenly it appeared that a Slytherin had found his way into their commonroom.
"Why hello, Severus!" said Dumbledore. "Want some grapes?"
"Aren't you gonna ask how I got in here?"
"Aren't you gonna say: Yes please sir I'd love some!"
Snape rolled his eyes and went to Sirius.
"So, Black. Word has it your quite a flyer"
"Word has it you're quite ugly"
"Word has it you're uglier!"
"…No it hasn't"
"Boys, please" said McGonagall. "Let's not argue now. And Mr Snape, you are more than welcome to join the celebration. As you can see we even have some Ravenclaws with us"
"No thanks, I gotta go plot some evil plans"
And with that, Snape stormed off to the Dungeons.

"If there's one guy you don't want to get steamed up, it's Snape" said Lily.
"'Cause he had an evil plan...ooga booga booga!" Dorcas wiggled her fingers.
Music begins:
(Tune: Gospel Truth II)

Marlene:
He runs the dungeons
He's known to be both dull and uncouth
He is as mean as he is greasy
And that's the quidditch truth
He has a plan to brew things up
And that's the quidditch truth

"Avery!" Snape yelled as he sat down in the Slytherin Commonroom. "Mulciber!"
Both Avery and Mulciber tripped down the stairs to the boy's dorm on their way down.
"Avery!" Avery made a salute gesture.
"And Mulciber!" Mulciber too.
"Reporting for beauty!" said both.
"Whatever. I have a riddle for you guys. How do you de-Gryffindor a Gryffindor?"
"I'm guessing feeding him with one of your weird potions" Avery suggested.
"That's right"

Later that evening, Sirius stumbled upon two Slytherins on one of his...late evening strolls, thinking of how thirsty he was.
"Hey, want something to drink?" one of them asked him.
"Boy do I!"
The strangers gave him a bottle containing a suspiciously green liquid and ran away. Sirius opened it and drank it.
"Black what are you drinking?"
It was McGonagall that had suddenly appeared.
"I don't know, but it tastes like cloudberry"
McGonagall had a look at it. "You don't know? Where did you get it?"
"Some Slytherins gave it to me"
That was enough reason for the bottle to be confiscated in McGonagalls' opinion. Shortly after she had strolled off, Sirius passed out completely.
When he woke up an hour later, two older Slytherins were staring down at him.
"What are you doing down there?" Narcissa asked.
"I don't know" Sirius sat up and looked around.
"Well get up!" said Lucius. "You ickle firsties aren't allowed outside the common room after 8!"
Together they headed for Slytherin, for that was what Sirius was now. Avery and Mulciber had even changed his uniform and re-sorted him while he had been unconscious. Little did they know that he never drank the entire bottle. And little did they know they had left behind his old Gryffindor tie, which lucky enough had been found by Narcissa.

"Everything was tragic" said Lily indifferently. "It had all happened so quickly and by the time anyone had time to react, it was too late"
Music begins:
(Tune: Gospel Truth III)

Dorcas:
Black is a Slytherin
But since he did not drink the last drop
He still retained his prankster act
So thank his lucky star
But McGonagall wept
'Cause she had lost a chaser so good
She had now lost both champion players
That is what they are
Though Snape's horrid plan
Was turned to mush like really old fruit
Black got less evil everyday
And that's the quidditch truth

(A/N: This is quite old, but it was crammed with grammar errors and spelling errors, and for some reason I kept going from past to present but that's fixed now, I hope, so I figured it was ready for FFNet now. We need more musical fics!)
