You'll End up with Colorado on Your Foot

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