Write a story, about a teenager in school who has one of those "Oh my God" funny moments that everyone laughs at in public.

Rules:

1. Main character has to laugh to. It can't be something humiliating like a public wedgie where main character would just feel mortified. Main character has to find some sort of comedy in the embarrassing situation.
2. It has to involve a crowd or at least a few people who see it in the story.
3. Has to happen on campus. Can't deviate to a different setting. (No school field trip stuff, ditching class, after school etc type scenes)
4. Keep it human please (Nothing mystical, mythical, magic etc.)
5. Write from a first person perspective.
