Bones?

In our city/suburban existence, we are so far removed from the original sources of our food that sometimes it's easy to forget that kids have no idea where much of their food comes from (Jewel, of course!)
Case in point: yesterday, K was sitting at our kitchen counter, finishing up some leftover popcorn. When it was nearly gone, he asked me, "Bubbie, can we make more popcorn? There's only bones left!"
