What's the weirdest thing YOU'VE done at school or in public?

So looking at the other question, I just realized....

I THINK I MASTURBATED IN THE SCHOOL AUDITORIUM.

WHILE PEOPLE WERE PRACTICING.

I can't remember if I did or not (I probably did) but now im ready to pass away so I want others to join me.

Give me the story you taking to your grave.
