A pig in your big toe!

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