Hmm I have two. One of them was when my brother hid a wrapped ring box for me on the tree. I had to scour the tree in order to find my present. I must have been no older than 10 at the time. The next one was when my mom got me the super nintendo. She had to hide it at a friends house. By that time I had mastered finding gifts, unwrapping and rewrapping them.

When my brother brought the box in, my mom had did that box upon box thing until I got to my gift.
