If you had a Nintendo Entertainment System in the '80s, you probably played Duck Hunt. It was a simple game -- you used a mostly accurate plastic gun to shoot digitized mallards while a dog laughed at your mistakes.

If you were like me, you probably wondered what was going on beyond that tall grass the hound jumped behind. Well, wonder no more! [via College Humor]:

So that's why I could hold the gun right to the TV screen and not hit a damn thing. And here I always thought it was because the NES Zapper was made for pennies by third-world country slave labor.
