Why did I get kicked out of school?

ok, here is how the day started. i came in with a bikini on because i was really hot. then during math cl i shouted out, "MATH IS BORING. I WISH I COULD PEE ON IT!" then at lunch i stole someone's pie and smashed it into my face. then i went outside at recess and shot someone with a bebe gun. why did i get expelled?
