My MadLib!

My great-grandfather used to tell me, "Don't chase after ships because you'll only end up with a necklace in your head." I never quite understood his advice until one Thanksgiving, I was gardening with my best friend Emily. All of a sudden, we found an underground tunnel! It was loud and spooky sounds came from deep within. Emily saw something interesting inside, jumped in, and I never saw her again. Great-granddaddy was right!
