Sirius Black and James Potter were the worst students Hogwarts had ever seen. And admittedly, also the best. Best at marks, best at magic, the very best at mischief, and especially best at quidditch. (Something they considered far more important than all the rest put together, except perhaps for mischief.) But they were also the worst. They were chaos and trouble personified in the forms of two boys, two best friends.

This was evident one cold, sunny morning in February, as students in Professor McGonagall's classroom scribbled down notes furiously, reflections of red and blue from the stained glass painting their faces. Except for one, Sirius Black and one, James Potter. James balanced precariously on the backs of his chair legs. He was meant to be keeping look out, but was instead tossing a nicked snitch up and down. Sirius meanwhile, was concentrating hard on transfiguring his parchment not into bits of wood (as had been assigned), but rather into something highly inappropriate. Something that would give James and him a laugh and maybe even earn them a disparaging look from Remus.

Professor McGonagall had already begun weaving her way through students and desks and floating bits of parchment (still singing, some were) as soon as she had seen the cheeky smirk on Sirius' face. She was spared the trouble of walking all the way over however, by the loud sound of James Potter falling off his chair and screeching "PANTIES" at the top of his lungs.

This was followed by a roaring laugh from Sirius, some sniggering, and one very angry Pamela Dodson storming up to Sirius and grabbing the panties all while muttering a flurry of curses in a general direction.

"Black, Potter, in my office after class. And detention for the pair of you, two weeks. You should be ashamed of yourselves!" McGonagall could not count the number of times she had said those words to these boys.

In her office, she glared down and Potter and Black's smirking faces, "Well? What have you got to say for yourselves?"

James and Sirius glanced at each other and smiled. "Why Professor, we were merely practicing…" Sirius trailed off.

"- Our transfiguration skills…" James jumped in.

"- Yes, as you say Minnie, practice makes perfect."

"Though we already are perfect James."

"Right, but I felt the need to point out our obvious talent to the rest of the class."

"Yeah, transfiguring parchment to panties" At which point James sniggered and Sirius tried his best to continue smoothly on "—is no easy feat."

This McGonagall could not deny them. The boys did have obvious talent. If they spent more time practicing magic and less time causing mischief, they would be top in class.

"That sort of behavior is inexcusable. 10 points from Gryffindor. Each." She said viciously when James opened his mouth to argue. "Now, apologise to Miss Dodson!"

Both boys turned sluggishly to Pamela, who having realized her wand was worthless, had taken to using fists before being restrained by Lily Evans. Lily was still clutching Pamela, who seemed ready to attack the boys at any moment.

"Pamela, Pam, Pammie. Now, now, let's not get our panties in a twist shall we? No pun intended, of course. It was all a bit of good fun." Sirius had gotten up from his chair and close to Pamela, touching her cheek as he spoke. Her anger seemed to falter. James came up on Pamela's other side and began tracing the pattern of the Gryffindor seal on her sweater.

If nothing else, the boys definitely knew how to use their considerable charms.

James came very close to Pamela's ear and with a quick wink to Sirius, leaned toward her and said softly "In our defense, Sirius did tell you to wear your nicest pair last night."

"So I knew what to transfigure my parchment into." Sirius grinned cheekily.

At this, Pamela flew at the boys, and Lily (after some hesitation) yelled "Protego!" before grabbing Pamela.

"You boys are vile creatures." She hissed viciously before dragging Pamela out of McGonagall's office.

"To know us is to love us Lily dearest!" James called out to her retreating back, his voice slightly muffled by the shield charm.

"Boys! This sort of behavior will not be tolerated at Hogwarts! I expect you both here for detention tomorrow, 8 o'clock." McGonagall glared at them as they sauntered out of her office.

"This is a hallowed institution of learning! Is that clear?" She yelled out to them. They turned around and grinned, Sirius even giving a cheeky wave before being hauled off by James.

McGonagall doubted Sirius Black and James Potter even knew what hallowed meant.
