Quiet days = trouble.

I don't own anything recognisable.

No house elves were harmed in the making of this fic.

It was a quiet day at Hogwarts.

In fact, it had been too quiet all week.

That should have warned the teachers that something was going to happen.

They never learn.

Quiet when the Weasley twins were around spells trouble for someone.

Fred and George were busy plotting somebodies doom

"How are we going to get him to take it?"

"Switching spells?"

"Nah, he would notice the change."

"Water bombs?"

"Too obvious"

"Coating his plate and cutlery?"

"… I think you're onto something there."

"Ok, he sits at the same place every day so that is easy."

"You run interference and I will do it tonight"

At breakfast the next morning:

Professor Snape sat down at the head table, checked his food for potions, as usual, found nothing wrong and began to eat.

A few minutes later he heard the sound of gagging. A number of students appeared to have indigestion.

Standing to leave he was shocked to hear snickering coming from the students and the staff, followed by mass vomiting.

Looking around all he could see were sick students.

Walking over to his snakes he was met with projectile vomit, screams and cries of "Pervert" "Put that away" "I'm blind, I'm BLIND" and "It's tiny".

Professor Dumbledore wrapped his robe around the confused potion master and firmly escorted him from the hall.

"Severus" Dumbledore began "I don't care what you do in your chambers. If you go to nudist colonies during breaks, that is your business. But you will come to meals and classes FULLY CLOTHED and keep your clothes on from now on IS THAT CLEAR!" He finished.

"But I…but…" stammered a confused Snape.

"Now, go and put some clothes on and we will forget this ever happened." Instructed Dumbledore.

Walking to the dungeons Snape pondered on what had happened. He could see his clothes, he could feel them. So what happened?

He changed into new robes and went to his first class.

"Potter is in this class. I can yell at him now" Snape thought maliciously.

Walking into the room he heard screams and saw students running for the exit.

"He's naked again" "Pervert alert" "I'm going to be sick again"

Hearing the cries of terror Dumbledore entered the potions classroom.

"I am a reasonable man Severus, but I will NOT ignore your blatant disregard of my instructions. Get DRESSED! One more problem and you will be fired. Understood?"

A confused and cowed Snape turned and walked into his office. He was not seen for the rest of the day. Two house elves that served Snape were later found dead from alcohol poisoning.

"Darn, that one had a down side to it."

"I don't think I have ever seen so many projectile vomits at the same time."

"What's next then? Or WHO is next?"

Manic laughter followed the twins down the hall.

A little story that would not get out of my head. This is the prank mentioned in my story "Eating...?"

I take no responsibility for lost meals, bad mental images or any psycological problems this may induce.
