I know it's probably already been done but the evil person in my head told me to do it anyway.

Chapter 1: If a classmate falls asleep, I will not take advantage of that fact and draw the Dark Mark on their arm.
History of Magic was probably the most boring class in hogwarts. Professor Binns never really noticed anything, he just kept droning on and on. That's why all of the students had fallen asleep and I was close to follow them when an idea came to me. This would be so funny!
I took the left arm of the person that was next to me and took one of my muggle permanent markers and started to draw. When I was done the image I placed his arm back to where it was and got up slowly.
I went next to the desk of my next victims and drew it again...
By the time I was done every single student in the class had a dark mark drawn on their arm and there was still ten minutes left of the periode. I decided to draw myself one.
When I was done I put the marker back in my bag and pretended that I was asleep. When the bell rang everyone got up and out of the class. Some of them never even noticed that they had something on their arm but some did and started accusing their friends.
All I have to say was that this was the funnest History of magic class that I've ever been to!
