(Some) Annoying Things To Do On An Elevator

• Say “~DING!!” at each floor.

• Say “I wonder what all these do?” And push all the red buttons.

• Make explosion noises when anyone presses a button.

• Draw a little square on the floor with chalk and announce to the other passengers: “This is my personal space.”

• Drop a pen and wail until someone reaches to help pick it up, then scream: “THAT’S MINE!!”
