Annoy-A-Teen

I was a high school teacher for four years. I loved those kids, but let me tell you, they annoyed the ever living crap out of me. The worst offense: eating Cheetos and then touching stuff in my classroom with cheesy fingers. Made me want to DIE. It's pay back time! At least, virtually. Annoy-A-Teen generates irritatingly high frequency sounds that most adults have lost their ability to hear, thereby targeting teenagers. God, I wish this app existed when I was a teacher. I would have used it as my primary method of discipline.
