These things might get you detention or suspension, but oh well.
1. Shout "AUSLLY!!!"
2. Put a Kick Me sign on the teacher's back while she's not looking.
3. Pretend to be on the phone. Pretend the phone's battery is dying and throw it on the ground when the teacher is looking.
4. Read a magazine and fangirl over One Direction.
5. When the teachers calls on you, scream "YOLO"
