HELP ME EXACT REVENGE ON MY YOUNGER SISTER AND HER FRIENDS FOR EATING ALL THEIR 🍕🍕🍕

I get home after slaving away at my part time job only to find that pizza was ordered and then promptly demolished before I even returned.
  1. I could push them...
    Aggressively!
  2. I could eat all these M&Ms?

  3. Get windex out and squirt them with it.
    I've done this twice.

  7. Wake up at 5 am, stick your fingers in the freezer for a full minute, go into her room and grab her feet under her covers.
    I did this once. It didn't occur to me to just use ice cubes instead of my fingers. But I feel like I got the whole experience that way. Disclaimer: might get kicked in the face.

  8. 1. Bite yourself 2. SCREAM AT THE TOP OF YOUR LUNGS UNTIL YOUR PARENTS ARRIVE. 3. Blame it on a sibling of your choice.
    I think I was a demon.

  9. 1. Fill a glass with milk. 2. Walk over to them and literally pour the milk on them. 3. Any punishment that results will be worth the story and the memory.
