Tell your teacher you recently stole away and confessed your romantic feelings for their husband/wife and jump out a window while they either stare in disgust at your lying and jumping out a window or cry in a corner.
Go ahead and be disruptive in class to the point where your Teacher walks up to you and tells you to stop. After that, tell the Teacher (If you're a Boy and if the teacher is a girl) that you want to **** them and tell them highly innapropriate jokes.
