Harry, Ron, and Hermione were all waiting patiently for their Potions lesson to begin. It was the first time ever that Professor Snape was late, and they couldn't wait to give him a smug grin.

Suddenly, the door flew open and he flounced in, as haughty as usual.

"Professor," simpered Draco Malfoy. "Is everything ok? You're twenty minutes late."

"Of course Draco," Snape said in his usual drawl. "I was just taking care of something."

"Like what?" Harry asked before he could stop himself.

Snape glared at him for a second before making a horrified face and beginning to sing:

"There's a man who lives a life of danger
To everyone he meets, he stays a stranger
With every move he makes
Another chance he takes
Odds are he won't live to see tomorrow

Secret agent man, secret agent man
They've given you a number
And taken away your name".

The class stared at him for a moment as a ringing silence filled the dungeon.

Snape frowned. "Class dismissed," he said, turning and exiting the room.

Ron grinned at Harry. "Wish every Potions lesson went like that!"

"Oh Ron, no you don't, you'd fail your O.W.L.S," Hermione said with a scowl.

Harry stood up. "C'mon," he said, going into the hall. They could hear hundreds of students singing, all different tunes, all blushing furiously. They passed Parvati Patil singing to Dean about how she had boots made for walking, and Lavender was belting out a long ballad about being misunderstood.

Chaos was reining the halls. And the students could not have asked for a better distraction.

Indeed, during charms, Professor Flitwick burst into song:

"Yes, I'm grounded
Got my wings clipped
I'm surrounded (by)
All this pavementGuess I'll circle
While I'm waiting
For my fears to dry

Someday I'll fly
Someday I'll soar
Someday I'll be something much more
Cause I'm bigger than my body gives me credit for

Why is it not the time?
What is there more to learn?
I've shed this skin that I've been chipping at
And I've never quite returned."

That class was also dismissed early. No matter where anybody turned that day, people were singing. Ron was still dashing away when someone would start singing as to not catch the bug. Harry, on the other hand, decided to write to Remus Lupin and see if he knew anything about the first time the hex had hit."

A/N: These are very short, I know, but this story is pet. I write in it when inspiration strikes, and when I feel like playing. Unfortunately, I'm not sure if this story will be up much longer, because I've heard we're not allowed to have song lyrics in our stories anymore. I'm not sure, but I'm posting it anyway. If it gets deleted, I'll post it somewhere else. Anyway, enjoy. If this doesn't get deleted, I have big plans for this story.
