1. Follow them around the house everywhere.
2. Moo when they say your name.
3. Run into walls.
4. Say that wearing clothes is against your religion.
5. Stand over them at four in the morning with a huge grin on your face and say "Good morning, sunshine"
6. Pluck someone's hair out and yell, "DNA!!!"
7. Wear a sticker that says, "I'm a retard"
8. Have 20 imaginary friends that talk to you all day.
9. Do what they actually tell you.
10. Jump off the roof, trying to fly.
11. Hold their hand and whisper to them, "I see dead people!"
12. At everything they say, yell "LIAR!!"
13. Tap on their door all night.
