Did anyone ever accidentally come across your Christmas Presents before Christmas Day?

I remember one time when I was a child, I was in my parents room and I opened the wardrobe and I found a Ghostbusters Gun. It was a torch that had slides if ghosts on it, so when you pressed the button it projected the images. When I told my mother that I had found it she told me it was my cousins Christmas present. Then on Christmas morning when I opened my presents I discovered that the Ghostbusters Gun was mine. It was a brilliant present.

Another Christmas I walked into my sisters room where I found my brother, mother and sisters playing an Atari 2600. They quickly turned it off and on Christmas Morning I discovered that the 2600 Atari was actually my Christmas present. They were trying it out themselves when I walked in on them all playing it.
