What was the worse thing you've done that pissed off your parents?

I think I was about five years old, and I had no one to play with, so I decided to play hide and seek by myself. I hid inside the laundry hamper in the bathroom. When it was time for dinner my mother started to call me, and then my father started to call me, but I didn't answer. I could hear them yelling and calling and searching for me all over the house, but I wouldn't answer. Finally my father came in the bathroom and must have heard something, because he lifted up the lid of the hamper and hauled me out, hitting me in the head the entire time.
