Whats the best thing your piggie does?

Whats the cutest/smartest thing your piggie does?

Mine is famous for knocking his bowl over, and if he knocks it over he will go over to it, step on it, then get off so it makes noise when it hits. I can also stand at the end of his cage, and ask him what he needs, and most of the time, he will go to whatever needs to be filled then come back to me. If his water is empty, he will go to it, act like hes drinking, then come back to me. He will also wheek if he needs something and im not in the room. He has different wheeks for if he hears snack sounds in the kitchen vs needing something. He is super smart, yet a derpy tater... lol
