The note that got passed around

No

When I was in high school a buddy of mine left his notebook behind class. I got it, when I was looking at it I knew whose it was. So during class I wrote like 1 sentience on every page, was trying to be funny.

Well, anyway, when he found it, he was going through the notebook reading it and laughing at what i wrote. The entire class, including the teacher was looking at the notebook as he was reading it laughing at it saying that's my handwriting etc. Anyway, got to a page and i wrote, isn't Mr. Smit a cum stain. The teacher in the class, he grabbed the notebook and said I'll be keeping this.

I wonder who did and what happened to the student that wrote it.
