Walk to the pencil sharpener for no apparent reason
Always forget a pen, then ask your neighbor for one every 5 minutes
Do that fake ripping sound with all of your tests and homework
When you teachers asks what you didnt get say, Well, I didnt get the first part, or the end part, and the middle-y part was kinda confusing.
Mock your teacher
During recess put rubber bugs on the bottom of the slide
Step on ketchup packets in the cafeteria
Put a thumbtack on your neighbors seat
Put a sign on your teachers desk that says, Mental and proud of it!
Always say your dog ate your homework&or cat&.or fish&.or hamster
Sing the Elmo theme song when your teacher is not in the room
Tattle on your friend for something really random
Hum loudly
Poke your neighbor
Read this list out loud during lunch
