The Sky is Falling!

When the acorns start to fall I think of the Chicken Little Story. I don't remember too much about the story except that Chicken Little gets hit on the head by (maybe) an acorn and freaks out.
I picked these up in the parking lot of the building my mother-in-law lives in. They have a couple of huge old oak trees. The driveway is full of acorns and you can hear then crunching under your tires.
