For me, it was an original NES (Nintendo Entertainment System) with Super Mario Brothers AND Duck Hunt.  I don't know that I had this same reaction, but then again, Youtube wasn't around in the late 1980's.  But I do remember how excited I was.

Were you ever this excited for one of your Christmas gifts?

Just use caution if you watch this at work.  Someone in the cube next to you may wonder if you're hiding and torturing a small child beneath your desk.
