Movies and Popcorn, what gives?

My niece made some popcorn tonight and when my kids saw and smelled
it, they all got the same idea to pop a DVD and watch a movie. I
mean, where in the world did it say that when someone eats popcorn,
they should watch a movie as well? Hmmm or is it the other way
around? Can;t we eat popcorn without watching a movie, you know, how
about just eating popcorn, period! Hehehe
