Disclaimer: I don't own anything, JK Rowling does.

Pairings: James/Lily, Sirius/OC

Summary: Insanity takes over Hogwarts for the whole month of April. Expectedly, the Marauders take credit for most of it, but, more surprisingly, Lily and her friends join in the fun too, to James's and Sirius's great pleasure. Includes a drunken Sirius, pranks kisses and general delirium. Now everyone to St Mungo's!

Author's Note: This is written for Cuban Sombrero Gal's challenge. I know this prologue is ridiculously short, I just wanted you to be intrigued! First chapter coming very soon.


Prologue

"You got it, then?"

The girl looked up at him; cold blue eyes met sparkling hazel.

"I am not stupid," the girl stated stiffly.

"I know!" James said quickly. "I was just making sure…"

James looked away, finding the girl's piercing gaze unnerving.

"It's not as if it was a master plan of an incredible complexity," the girl rolled her eyes. "All I have to do is make –"

"Don't!" James interrupted her, looking around warily. "You mustn't say it, in case somebody hears us."

The blonde girl chuckled as she realized James was serious.

"You're desperate," she said.

James turned to her and had to make an effort to smile charmingly.

"But, then, I don't mind that," the girl admitted.

James smiled again as she left, but this time his smile was undoubtedly tainted with mischief. Lily Evans will have a special day tomorrow, he said to himself.
