AN: This is taking place in the Great Hall sometime after Harry and Ginny start dating...I don't know why, it just formed that way in my mind .

Laughter
"Muahahaha!" Hermione thought carefully then nodded.
"Not bad, Ginny," she told her friend with a smile. "Ron, you next."
Ron cleared his throat, smirked at his girlfriend and gave a deep throaty chuckle. "Heheheheheheh."
Hermione shivered and Ginny sighed. "Go ahead 'Mione, say it. Ron's always had a better evil laugh then me." Hermione could say nothing and just nodded in agreement.
Ron smiled haughtily and nodded at Harry. "It's your turn, mate. Think you can do any better?"
"Of course! Muahahaheheheha!" Harry smiled expectantly as his friends looked at each other with shocked expressions.
"Er…Harry…" Ginny looked at her boyfriend pityingly but couldn't find the right words. Ron did no better. The redheads looked to their official referee for help.
"Harry, I'm sorry…" started Hermione slowly. "But that was horrible. It sounded like a strangled giggle. Not evil at all."
Harry groaned as the other Gryffindors sitting nearby laughed at Hermione's frank assessment. Suddenly the laughter stopped.
"The know-it-all is right again, Potter. There's a reason you're the savior of the wizarding world: you're evil laugh is pathetic! You could never be a dark lord with a laugh like that!"
Harry turned to look at the Slytherin behind him. "If you know so much about evil laughs, Malfoy, why don't you try it?" Even Crabbe and Goyle, standing behind Malfoy, looked smug.
"Buahahahahaha!" The Gryffindors all frowned as Hermione reluctantly acknowledged that Malfoy's laugh was the best yet.
"Hehehehahahah!" The insane cackle of laughter sent shivers down everyone's spine, even the Slytherins. Heads swung around to focus on the little Ravenclaw who'd produced the most evil laugh they'd ever heard.
"Hello, Luna," greeted Hermione quietly, still shaking.
"What's brought you over here," asked Ginny as she suppressed another shudder.
"Who the bloody hell taught you to laugh like that," asked Ron, staring at Luna with an unabashed expression of shock.
"Not even the Dark Lord laughs like that!"
Harry frowned at his rival. "It's pretty close though." Malfoy thought about it and nodded his agreement. Luna just smiled.
Up at the staff table, Professors Snape and McGonagall cancelled the eavesdropping spell before looking at the Head of Ravenclaw House with astonishment.
"Now you know why we no longer hold evil laughter contests in Ravenclaw House."
